Welcome Note

It is exactly ten years ago that a trailblazing technology fundamentally changed our lives with the introduction of the smartphone. At the same time, a similar revolution

also took place in the field of biomedical research: Scien-tists generated induced pluripotent stem cells (iPS cells) from mice and human beings. A further revolutionary tech-nology – genome surgery using the CRISPR/Cas system – is just five years old.

These highly innovative biomedical technologies present entirely new approaches to researching diseases. Stem cells have become an essential instrument for basic bio-medical research, for the development of drugs and for testing active substances. They also have potential for the development of new treatments for patients.

German stem cell research is making an important con-tribution towards this effort. This is reflected not least in the great response to the recent call for proposals in the field of innovative stem cell technologies for individualized medicine issued by the Federal Ministry of Education and Research (BMBF). Over the next three years, the BMBF will provide funding of approximately 21 million euros for a to-tal of 13 research collaborations nationwide with the aim of translating stem cell technologies into medical applica-tions.

The working groups which are now being funded are profiting from the existence of the German Stem Cell Net-work – GSCN. The BMBF has been funding the development of the GSCN since 2013 and the latter has quickly established itself as an important na-tional forum. It serves as the contact point for international partners and industry as well as communicating with soci-ety at large. The GSCN’s annual conferences have become a central meeting place for the German stem cell research community.

This year’s GSCN magazine explores the potential and prospects of stem cell research in Germany, highlights ca-reer opportunities as well as ways to familiarize a wider public with the world of stem cells. Stem cell research is a key driver for innovation in the medicine of the future and I sincerely hope that the Network will continue to maintain and expand its commitment to science and industry.

GSCNare the

Now in its fifth year, the German Stem Cell Network GSCN has worked tremendously hard and achieved a great deal over the last four years. Today, the GSCN

plays an invaluable role in bringing together stem cell re-searchers from across the spectrum, connecting research projects and advising political decision-makers on issues relating to stem cell research. It is serving as a critical and expert guide in the public discourse on stem cell research and the opportunities it holds to develop new therapies in the future.

Research undertaken in the last few years has shown that stem cells are of fundamental significance in the develop-ment of disease in older age. We now know that 50 per-cent of 70-year-olds have mutated stem cell clones in their blood, which are a cause of cardiovascular diseases and cancer and reduce life expectancy in old age. Recent studies have shown that cell reprogramming of induced pluripo-tent stem cells (iPS cells) can be used to develop models to investigate the cause of diseases and test new therapies to mitigate their effects.

In view of the rapidly increasing potential of stem cell re-search, the GSCN is becoming ever more important as a mediator of knowledge transfer, as a communication plat-form, as an advisor to policymakers and the general public, and as a catalyst in the development of stem cell research. At the same time, however, the funding for the GSCN from the Federal Ministry of Education and Research (BMBF) is coming to an end this year and the future financing of the GSCN has not yet been secured.

The uncertain future of the GSCN is indicative of a gener-al weakness in the German research system. Profession-al associations in Germany are usually financed through membership fees and by partners from industry. In new, emerging research fields like stem cell research, the funds generated from these sources are not sufficient for the professional association to fulfill its key role in develop-

ing the research area. One of our main tasks this year is therefore to consult with political representatives to find possible solutions that will enable the GSCN to continue its highly successful work and support the further development of stem cell research in Germany. A conceivable option, for example, would be a transitional financing scheme.

Let us therefore make a concerted effort in 2017 to ensure that the GSCN is able secure the funding it needs to con-tinue its successful work in supporting the development of stem cell research and driving its potential for translational application.

I would like to invite you all most warmly to the next an-nual conference of the GSCN in September 2017 in Jena, where you will be able to gain an overview of the latest developments and opportunities in stem cell research. Our relatively young research field is undoubtedly one of the most dynamic areas in biomedicine. I look forward to further consolidating its position in Germany, to my work in the GSCN this year, and to leading this valuable network into a secure future.

I hope that you find this latest issue of our annual magazine an interesting and inspiring read.

GSCN President K. Lenhard Rudolph on his visions for the GSCN

“The GSCN is the largest network on stem cell research in Germany”

Annual GSCN Magazine 2016/17 9

INTERVIEW WITH K. LENHARD RUDOLPH

The German Stem Cell Network (GSCN) faces some major challenges in 2017. The main task now is to secure the achievements of the last years for the medium and the long term. This will require a concerted effort from all sides. As active president, K. Lenhard Rudolph will be in charge of structuring this process this year. The work of the GSCN over the last four years, including the GSCN annual conferences as the highlight of the scientific year and a wealth of other activities, is held in high regard on a national and inter-national level. This reputation needs to be maintained and consolidated further. In an interview with the GSCN annual magazine, K. Lenhard Rudolph spoke about his visions, plans and objectives for the network.

GSCN Annual Magazine: What does the German Stem Cell Network mean to you?

K. Lenhard Rudolph: For me, it is above all a network that brings together researchers from all fields of stem cell re-search. The GSCN is an essential platform for intensifying collaboration, developing new ideas and alliances, and ini-tiating new interdisciplinary approaches. This is where re-searchers meet to share new unpublished data and to push the field ahead.

The GSCN Annual Conference is the number one gathering in Germany and Europe for the stem cell research commu-nity. The conference has a very important catalyst function in Germany because this is where alliance projects are in-itiated. The GSCN is the platform that brings key people working in the field together. It allows us to develop new concepts within Germany and to position ourselves joint-ly for international projects. Of course it is also important to participate in other international meetings to meet col-leagues from abroad and keep up with the latest develop-ments in research outside of Germany.

As president of the GSCN, what are your objectives for 2017?

K. L. R.: It is important to me that the inspiring nature of the GSCN – with around 400 stem cell researchers partici-pating in the annual conferences – is maintained and used even more effectively. I would like to give additional weight to the conference formats where everyone sits together

and discusses themes that go beyond the individual work-ing groups and plenary sessions.

There is a big question mark hanging over the future of the network. What do you consider feasible? What ma-kes most sense?

K. L. R.: Stem cell research is a very important research area to further our understanding of organ function main-tenance, aging, and the development of disease and is thus hugely relevant to society. The GSCN is the largest network for stem cell research in Germany and the most important platform for the scientific advancement of this field. The continued operation of the GSCN is therefore a high-in-terest issue. Members of the GSCN board are in ongoing dialogue with various research institutes and the Federal Ministry of Education and Research to explore all possible options to continue the work of the GSCN post 2017 and find a viable solution.

The GSCN has published a white paper on stem cell re-search. What response can we expect from policymakers and what can policymakers expect from us?

K. L. R.: The white paper illustrates the dynamics and po-tential of stem cell research. Public debate is also increas-ingly focusing on the future areas of application of this research. It is now time to use these opportunities and establish Germany as a major location in the international arena in this research area for the long term. This needs to be understood and backed by policymakers. The main objective of our paper was to point out these opportunities and recruit the political support to make the most of them.

What changes would you like to make to the GSCN Con-ference?

K. L. R.: I would like to further promote scientific exchange between all participants and address the research themes more intensively in the plenary sessions so that we can dis-cuss them all together. Of course I would like to keep the fo-cus on contributions from German research institutes, but I would also like to increase the international integration of the GSCN, particularly with our partners in Europe. The GSCN Conference is the ideal platform for this endeavor.Ph

10 Stem Cell Research: Potentials & Perspectives

INTERVIEW WITH K. LENHARD RUDOLPH

Which themes could the GSCN expand on further in fu-ture?

K. L. R.: The focus this year is on the aging of stem cells. There is increasing evidence that age-related loss of func-tion and mutations of stem cells can cause dysfunctions and disease in old age. Other emerging areas are the impact of commensal bacteria in the gut, for example, on stem cell function, computer-assisted approaches in stem cell analy-sis and the individualized prevention of diseases based on stem cell changes.

What basic themes would you like to advance in stem cell research?

K. L. R.: I would like to advance our understanding of the connection between stem cells and aging. And there are very practical reasons for this. For one thing, mutations in stem cells expand clonally in old age. Around 50 percent of people aged over 70 are affected by this and it impacts both on their life expectancy and the probability that they will develop a disease. In my opinion, this means we should be taking a very close look at stem cells in these processes. Another aspect concerns the extent to which the aging of stem cells influences the development of cancer and can be identified as a cause of the disease. That would affect all or-gans and tissues although research here has until now been limited to the hematopoietic system, i.e. blood production. This is a big emerging field.

Stem cell clones that expand and exhibit gene mutations have been shown to exist, and we know that they grow with increasing age, but we have no idea why that is so. What are the selection mechanisms and what impact does life-style have? Is it possible to slow down the rate of clone mu-tation? I would be interested to find out what role sports, movement and nutrition have here – these are all extremely exciting topics with regard to the origin and development of mutations. Even if these topics don’t seem to have much to do with stem cells at first glance, they do have an impact on them. An example is the microbiome. We have initial ev-idence that the colonization of the gut affects stem cells. I would like to add a systems biological approach here.

Stem cell research is, in its very nature, a crosscutting field of research and as such extremely important. While stem

cells are a rare type of cell, they are important and I believe it is crucial to further our understanding of them. Not only are they the foundation of life for maintaining organisms, they also influence the regenerative capacity of our organs as we get older.

What has been the most important research finding for you over the past few years?

K. L. R.: For me it is the finding that mutated clones are not a rarity but are in general a part of the biology of the aging human. There is evidence that these clones should not just be regarded as biomarkers but have a causal connection to the development of disease in old age. This is a whole new field of research in my opinion as it opens up the possibility of endogenously influencing the body’s own stem cells with targeted medicine in order to prevent or at least slow down the development of disease in old age.

Another important new area of research is based on ex-periments that show that changes in the epigenome in old age lead to a malfunctioning of stem cells thereby reducing organ function and regeneration. Researchers from the US have now been able to show that epigenetic changes of this kind are in principle reversible which could, in turn, pro-long the maintenance of organ function in old age. This is also a very promising approach in my opinion.

What are the highlights for the GSCN in 2017?

Our annual conference in Jena from 11 to 13 September will of course be a big highlight for us. We are preparing a first-rate program that will include very interesting key-notes, great locations and lots of exciting events. I hope that a large number of researchers will come to our open and academically rigorous Jena. I am also already looking forward to this year’s edition of UniStem Day, an exciting event with high-school students that really impressed me last year and will take place on an even bigger scale in Ger-many this year. Beyond that, our working groups are be-coming increasingly active and there are lots of different workshops in the pipeline, a Gordon conference on stem cells, the NRW meeting in May, supported by the GSCN, and the ISSCR in Boston, in which the GSCN will also be partic-ipating again. This wealth of activities shows just how vital and dynamic our network continues to be in 2017.

Karl Lenhard Rudolph is scientific director of the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) in Jena, professor for molecular research on aging at the Friedrich Schiller University Jena (FSU), former president of the German Associ-ation for Aging Research (DGfA) and, since September 2016, active president of the German Stem Cell Network (GSCN). The renowned researcher on aging and physician has received many awards for his work, including the Leibniz Prize in

2009 and the German Cancer Award of the German Cancer Society in 2015. His main research area is the origins, processes and consequences of stem cell aging.

Rudolph’s research findings have been published in well over 150 publications in re-viewed international journals, on subjects including the clonal dominance of mutated

stem cells, telomere shortening in stem cells and the influence of external factors such as nutrition on stem cell functionality.

Stem cell films for events

In the last three years the GSCN has made eight

short films on German stem cell scientists and their research. The eight stem cell researchers por-

trayed so far are Mag-dalena Götz, Anthony

Ho, Andreas Trumpp, Hubert Serve, Andreas

Zeiher, Tobias Cantz / Mi-chael Manns, Nils Hoppe and

Ulrich Martin. New films planned for 2017 will feature K. Lenhard Rudolph, Claudia Waskow and Jürgen Knoblich. The films provide an insight into current research on heart, blood, liver and neu-ronal diseases and the corresponding stem cell research. All film portraits are available in English and German and are ideally suited for presentation at public events. They are available on the GSCN website under the “Resources” tab.

Travel Awards – an example from ISSCR 2016

Via its working groups, the GSCN grants travel awards to young scientists wishing to take part in a conference or workshop with a poster presentation. And it’s well worth the effort. Stefan Hauser from Tübingen was one of six re-cipients of a travel grant to the ISSCR Annual Meeting 2016 in San Francisco. Here is an extract from his report: “One of the most inspiring talks for me was the presentation by Shinya Yamanaka. The first part of his talk “Reprogramming

of Cells and Scientist” focused on a more personal level on the discovery of iPSCs and how this changed his scientific life. He said that “iPSC discovery reprogrammed myself” and led to “spending a lot of time talking with people in government and industry and banks, and also spending a lot of time on fund raising … But some portion of myself is refractory to reprogramming. That part tells me I should enjoy basic re-search.” This part was quite inspiring to me and is important for the translational aspect of stem cell research. … Another highlight of the ISSCR annual meeting was the poster session every evening where hundreds of projects were presented in parallel. Several encounters with poster presenters led to fruitful discussions, insights into adjacent fields of research, ideas for my own research, and potential contacts and co-operation for the future. Apart from ‘pure’ science, it was fantastic to join the GSCN WunderBar Evening. The German stem cell scientists met at the ‘Thirsty Bear Brewing Com-pany’ and had a great evening with inspiring scientific as well as non-scientific discussions, great beer and tapas in a relaxed atmosphere which led to new cooperation and ideas and was a helpful way to meet new people and get to know each other better.”

There are now four fixed dates a year to which GSCN mem-bers and researchers in Germany can apply for travel grants to international stem cell conferences: by 28 Feb. for events taking place from 1 April to 30 June, by 31 May for events from 1 July to 30 Sept., by 31 Aug. for events from 1 Oct. to 31 Dec. and by 30 Nov. for events from 1 Jan. to 31 March the following year. Applications should be sent to the GSCN central office by the respective deadline. They should in-clude a letter of motivation and the contribution submitted for the event in question.

The Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) has dedicated to biomedical aging research since 2004. More than 330 members from over 30 nations explore the molecular mechanisms underlying aging processes and age-associated diseases. It is one of only two national research in-stitutes on basic mechanisms of aging in Germany. The main aim of research at FLI is to delineate how aging leads to the development of tissue dysfunc-tion and diseases in the elderly. If the understan-ding of the aging process contributes to the extensi-on of healthy lifespan, the strains on society can be

minimized and the society’s future development will be enriched by the wealth of knowledge and experi-ence older people possess. As one of 91 institutes of the Leibniz Association, the FLI is publically funded by the German Federal Ministry of Education and Research (BMBF) and the State of Thuringia.

GSCN Awards 2016

In 2016, the GSCN Young Investigator Award went to Dr. Leo Kurian from the Center for Molecular Medicine Co-logne (CMMC) at the University of Cologne. The recipient of the GSCN 2016 Female Scientist Award was Prof. Dr. Clau-dia Waskow from the TU Dresden. The GSCN 2016 Pub-lication of the Year Award honored Dr. Guangqi Song, Dr. Martin Pacher, Prof. Michael Ott and Dr. Amar Deep Sharma from the REBIRTH Center and the TWINCORE Center of the Hannover Medical School (MHH) for the publication “Di-rect Reprogramming of Hepatic Myofibroblasts into Hepat-ocytes In Vivo Attenuates Liver Fibrosis” in the journal Cell Stem Cell.

Wunderbar: GSCN at the ISSCR in San Francisco

First Stockholm, then San Francisco: The GSCN organized its second WunderBar Evening at the Annual Meeting of the ISSCR in 2016. The networking meet of GSCN members, friends and guests in San Francisco was a great success. Ninety guests attended the evening event that was held in a local brewery and provided lots of opportunity for person-al networking. The 2017 ISSCR Annual Meeting will take place in Boston and the GSCN will certainly be holding an-other edition of the WunderBar Evening there.

Trouble shooting – Non-PI Meeting in Hannover

In the follow-up to the GSCN Conference in Hannover, 23 non-PIs met to discuss trouble shooting in research, to report on methods, ideas and stories about research fail-ures and lab crises, and talk about these together in a joint forum. The meeting, held under the motto “learning from mistakes”, gives scientist the chance to share their expe-riences and learn from each other. The response to this second non-PI meeting of the GSCN was very positive and work has started on preparing future meetings on themes relevant to young scientists.

Explaining and discussing regulations – GSCN-PEI Workshop

“This was a highly informative workshop on translation, clinical trials and the many regulatory issues that we as sci-entists have to observe,” says GSCN managing director Dan-iel Besser, reporting on the information event on regulato-ry processes hosted by the Paul Ehrlich Institute (PEI) as a one-day workshop in November 2016. The participants found the clarification of the regulatory procedures in-volved in translation extremely helpful, as it gave them lots of pointers on how to save time and money in application procedures. The PEI advises scientists on how to effectively and successfully apply for clinical trials.

Grant-Writing Workshop – watch out reviewers!

Twelve young scientists met in Ulm for two days to practice writ-ing grant applications and learn tips and tricks to make their applications to the EU and other funding bod-ies successful. Hartmut Geiger, who organized the workshop, reported: “The Career Development working group of the GSCN (Insa Schroeder, Hartmut Geiger) held a grant-writing workshop in Novem-ber in Ulm. It was booked out very early on and the par-ticipants told us that it was very helpful. We hope that all participants will be able to put what they learned to use in the near future and be successful in their applications. Watch out reviewers, from now on all applications for stem cell research will be perfectly worded!”

Satellite sessions and supporting conferences

As in previous years, the GSCN was very busy in 2016 pre-senting and promoting stem cell research at the conferen-ces and meetings of other associations. The GSCN helped prepare two sessions at the conference of the Interdiscipli-nary Group for Laboratory and Flow Cytometry (IGLD) that took place in February 2016 in Hamburg. Speakers in a session on organs and organ models from stem cells were:• Magdalena Renner, IMBA, Wien: Embryonale menschli-

che Gehirne aus Stammzellen• Tobias Cantz, Hannover Medical School: Reprogrammi-

At the 49th Annual Meeting of the GSCN partner organiza-tion German Society of Transfusion Medicine and Immuno-hematology (DGTI) held in September 2016 in Nuremberg, the GSCN organized another successful satellite session, as it had already in 2014 in Dresden and in 2015 in Basel. Speakers at the session were:• Gerald Schumann, Paul Ehrlich Institute, Langen: Repro-

gramming triggers mobilization of endogenous trans-posable elements in human induced pluripotent stem cells – consequences for host gene expression

• Robert Zweigerdt, Hannover Medical School: Myocardial regeneration by human pluripotent stem cells

• Thomas Brabletz, Universität Erlangen: Metastasis: can-cer stem cells, microRNAs and EMT

• Susanne Kleber, DKFZ Heidelberg: Cancer stem cells in brain tumor initiation and progression

In February 2016, the first international symposium of the ISSCR in Germany took place in Dresden. The GSCN sup-ported the event financially and logistically, through its members on the program committee, through its participa-tion in evaluating the submitted contributions and by hold-ing a very successful breakout session on 3D cultures and organoids with Julia Ladewig (Bonn), Michael Karl (Dres-den), Jürgen Knoblich (Vienna, Austria) and Motosugu Ei-raku (Kobe, Japan).

PluriCore Network Meeting in Berlin

May 2016 saw the second meeting of the PluriCore Net-work. Forty-one experts on human iPSCs from 20 institutes convened in Berlin with the objective of elaborating guide-lines for quality assurance in the transfer of cell lines and in cells and tissues earmarked for reprogramming. Other topics on which the researchers shared their experiences included the reprogramming, differentiation and genome editing of pluripotent stem cells. Guest speakers from the Salk Institute in San Diego, the Robert Koch Institute and the Max Planck Institute in Munich reported on the latest developments in core facility management, methodology and ethical issues. Based on the findings of the meeting, a standardized transfer form was developed that contains the most important information on cell and tissue samples, as well as templates for consent forms and for informa-tion and ethics sheets for donors taking part in iPSC trials. These are available on PluriCore Network’s website (www.gscn.org/de/RESSOURCEN/DeutscheStammzell-CoreEin-heiten.aspx).

GSCN and Schering Foundation develop teaching materials for schools on stem cells

The Schering Foundation and the GSCN have developed four teaching modules on current stem cell research for senior high-school students. The teaching material is free-ly accessible for everyone in digital form and can be used by both teachers and students in class. The modules are designed in a conference format and aim to close the gaps between current stem cell research, genetic engineering, applied research and the presentation of stem cells in standard school biology books. The material is available for download at www.stammzellen-verstehen.de.

UniStem Day 2016 & 2017

What began as a pilot project in 2016 is set to become a calendar fixture as of 2017: UniStem Day. The European day of stem cell research in 2016 was such a success in the eight participating German cities that all the institutes are keen to take part once again in 2017 and the number of registrations received is even higher than last year. On 17 March 2017, scientists and school students in Heidelberg, Hannover, Bochum, Jena, Bonn and Dresden, Berlin and Münster and other cities will once again be spending the day teaching and learning about stem cell research. For more information, go to www.unistemday.de

The Max Planck Institute for Heart and Lung Research, located in Bad Nauheim, investigates developmental processes of organs in the cardiovascular system and the lung.

A second focus is molecular and cellular processes during the formation of diseases in heart, blood vessels and lung, including remodeling processes in these organs. Scientists at the institute search for new approaches to support repair and regeneration of the affected organs.

The MPI closely cooperates with universities in Frankfurt, Gießen and Marburg. It has become a major part of various federal and state excellence initiates and contributes to two “Gesundheitsforschungszentren”.

4TH ANNUAL CONFERENCE OF THE GSCN

This year’s GSCN Annual Conference in Hannover proved once again to be the most important annual meeting for stem cell researchers in Germany. Around 400 scientists met in the Lower Saxon capital for three days of intense com-munication and exchange on recent developments in the field. The top themes were the latest trends and techniques in organoid technologies, which are maturing at a rapid pace, the “new” discovery of extracellular vesicles, and tissue engineering. Ethical considerations were a major topic in a symposium held in parallel to the conference. A new compo-nent of this year’s GSCN meeting was a technology transfer exchange.

Once a year, the German Stem Cell Network (GSCN) brings together researchers from across Germany for a few days of intensive scientific exchange. This

year’s three-day conference was held at Hannover Medical School (MHH) and revolved around new techniques, re-sults and knowledge in stem cell research. The researchers made the most of the plentiful opportunities for lively dis-cussion and debate at the poster presentations, sessions, plenary symposia and evening events. An industry exhi-bition was held in parallel, giving researchers the chance to network with corporate lab suppliers and specialists in cell culture technology and molecular biology. The event has grown from year to year and in 2016 it consisted of 35 booths spread over several stories.

On Monday, Minister-President of Lower Saxony Stephan Weil, opened the conference with a warm welcome and proved to be very well-informed on stem cell issues. Follow-ing brief opening addresses by MHH President Christopher Baum and GSCN President Uli Martin, the conference start-

ed off with some exciting news. Keynote speaker Alexander Meissner an-

nounced that he is leaving the Broad Institute in

Cambridge (US) and coming

to Berlin in

4th Annual Conference of the German Stem Cell Network from 12 – 14 September, 2016 in Hannover

Novel trends and technologies in stem cell research

2017. As director of the Max Planck Institute of Molecular Genetics he will be in an excellent position to contribute to German stem cell research. In his lecture, he presented in-teresting new data on mechanisms of epigenetic regulation in stem cells and over the course of their development. It turns out that few CpGs show changes in their meth-ylation patterns during normal early embryonic development. Regions generally lie far above of developmentally regulated genes, and yet play important roles in their expression. In the second opening keynote of the conference, Sean Morrison from UT Southwestern, Texas (US), reported on findings in blood stem cells and their interactions with the perivascular stem cell niche. Mor-rison presented the latest data on the function of the chemokine CXCL12 in Tcf21-positive stromal cells and their role in establishing a niche for hematopoietic stem cells. The leptin receptor regulates the dif-ferentiation of stem cells of the bone in osteoblasts and adipocytes in the bones of the limbs. Leptin/Leptin-R activates the Jak2/Stat3 signal-ing pathway and promotes adipogenesis. Morrison also ad-dressed new findings on the role of osteolection (CLEC11a) in the maintenance of the adult skeleton. The findings shed light on the regulation of bone homeostasis and how the niche for hematopoietic stem cells is established and main-tained in the bone marrow.

On the first evening of the conference, Hiroshi Nagashima from Meiji University in Tokyo, Japan, gave a lecture on the generation of human organs in pigs. This branch of re-search has become increasingly important in the last few years due to the shortage of donor organs available for transplantation. However, the ethical implications of these technologies remain controversial. Hiroshi Nagashima’s presentation focused on his lab’s efforts to grow a human pancreas in a pig model. By changing the gene expression of Pdx1-Hes1 (the Pdx1 gene plays a key role in the for-mation of the pancreas), a genetic model was developed in which the animals no longer form a pancreas of their own. Exogenous stem cells from normal pigs, which differenti-ate into pancreatic cells, were able to completely form the organ during embryonic development, allowing the geneti-cally modified pigs to survive. The team is now planning to generate models for other organs. The long-term objective is to use human cells to generate “humanized” organs in pigs, but this still requires a number of technological and Ph

ethical issues to be resolved. Another important lecture on a new animal model was held by Thomas Eschenhagen from the Medical Center Hamburg-Eppendorf (UKE) as part of the Presidential Symposium. Eschenha-gen presented data from his working group on the transplantation of engineered heart tissue (EHT) differentiated from induced pluripotent stem cells (iPS cells) and endothelial cells in guinea pigs. The animals were transplanted with human EHT seven days following injury to the cardiac muscle. After 28 days under immuno-suppression, the transplanted cardiac muscle tissue in the scarred tissue had grown, vascularized and formed some electrical connections. The findings show that human 3D heart tissue can be built into the injured heart and rais-es hopes that this could lead to new therapies in treating heart attacks.

Both areas – basic research and clinical translation – re-quire a better understanding of the complex cellular and molecular clues underlying pluripotency and linage-spe-cific differentiation. This complexity is further extended by the diversity of 2D and 3D culture platforms applied in the field. Focusing on the transition of pluripotent stem cells (PSCs) into definitive blood cells, in his keynote lecture,

Peter Zandstra presented impressive progress on how the design of “in vitro niches” combined with computational

modeling of “stem cell behavior” can be applied to direct PSC differentiation into hemogenic mesoderm, and

ultimately mature T-cells. Moreover, once blood progenitors have emerged, successful mainte-nance of these progenitors in a “blood forming niche” was demonstrated, reminiscent of the endogenous hematopoietic stem cell niche in

the body. In conclusion, Peter highlighted how engineering principles and theoretical modeling

can be successfully applied to the very practical chal-lenges of translational stem cell research, providing impor-tant stimulation to the field.

Pete Coffey‘s lecture was canceled due to illness; two young researchers jumped in with excellent presentations. Boris Greber from the Max Planck Institute for Molecular Bio-medicine in Münster gave a lecture entitled “Principles of cardiac induction in human pluripotent stem cells” and Chao Sheng from the Institute of Reconstructive Neurobi-ology of the University of Bonn spoke on “Blood-derived stable induced neural stem cells: Preservation of age-re-lated DNA methylation patterns and application to disease modeling.”

18 Stem Cell Research: Potentials & Perspectives

4TH ANNUAL CONFERENCE OF THE GSCN

A pioneering feature of the GSCN conferences is the amount of the program dedicated to talks by up-and-coming young scientists. GSCN working groups select a program of presentations from the best abstracts for concurrent sessions. The partic-ipants of the online evaluation of the confer-ence were full of praise for this approach, with 79 percent rating the structure of the confer-ence as “very good” or “excellent”. “For the 2017 conference in Jena, we will try to organize even more plenary sessions alongside the Presidential Symposium and the keynotes,” said GSCN managing direc-tor Daniel Besser, “but the basic structure of the conference is our trademark and also provides a great opportunity for young researchers to present their data. The survey clearly

confirms this view.” In 2016, 184 ab-stracts were submitted for the con-

ference and evaluated by a jury. The chosen papers were organ-

ized into a total of 14 sessions reflecting current trends and top themes in stem cell research. The field of organoids is still developing

exponentially and becoming increasing-ly differentiated into subfields for each organ.

Beside a complete session on organoids in “Technologies in stem cell research”, Alexander Kleger (University Medical Center, Ulm) presented a novel approach to direct human pluripotent stem cells towards pancreatic organoids (POs) resembling acinar and ductal progeny in the session “Tissue engineering and organoids”. Upon orthotopic transplanta-tion into the murine pancreas, these POs formed normal pancreatic ducts and acinar tissue resembling fetal human pancreas. By applying this differentiation platform to mod-el pancreatic facets of cystic fibrosis (CF), the group was able to demonstrate that pancreatic commitment occurred unhindered in CF patient-derived iPS cells both in vitro and in vivo. Interestingly, the cells mirrored the CF-phenotype on a functional and global gene expression level and can thus be used for drug screenings and the testing of new therapeutic approaches.]. Further, Rasmus Freter (LICR, Oxford, UK) introduced his stem cell reporter OSCAR in the working group session “Somatic stem cells and develop-ment”. The lab has shown previously that adult stem cells of at least seven different lineages show decreased rates of mRNA transcription, marked by dephosphorylated RNA polymerase II.

Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC)Excellent stem cell research at the MDC in Berlin

The MDC is a biomedical research center in the north of Berlin. Many of its research groups work with stem cells, which often serve as a mo-del system for the investigation of the molecular causes of diseases of the cardiovascular system, the nervous system or the immune system, cancer and developmental disorders. Also, the application in therapy is being investigated.The center‘s Scientific Director Prof. Martin Lohse says: „We are very well-connected with clinical researchers and offer excellent infra-structures for stem cell research and animal ex-

periments. This makes the MDC an excellent place for working with stem cells. We will even expand our expertise in the field in the near future.“The Berlin Institute for Health (BIH), which was founded by MDC and Charité, will also strengthen its stem cell research by recruiting scientists for the areas of humanized models systems and cell engineering. A core facility for induced pluripo-tent stem cells (iPS cells) is maintained by both MDC and BIH and provides the scientific staff with support and expertise in obtaining and modifying iPS cell lines.

cells, it was possi-

ble to visualize dormant adult

stem cell induction and differentiation in

intestinal organoids using timelapse microscopy and FACS.

This reporter will be useful for the identi-fication and isolation of pure dormant stem cells from

many tissues as well as the screening of culture conditions for the expansion of immature stem cells in vitro.

MSCs have been applied in many clinical trials to treat various diseases. In contrast to the original hy-pothesis that MSCs home and integrate into affected tissues, in many diseases they seem to exert their therapeutic functions in a paracrine rather than a cellular man-ner. In the session “Stem cells in regen-erative therapies” Verena Börger (Uni-versity hospital Essen) presented data showing that extracellular vesicles from MSCs, such as exosomes and microvesi-cles, can exert comparable therapeutic func-tions in several disease models as the MSCs themselves. The researchers are currently focusing on improving their MSC-EV production and quality assur-ance platform with the aim of applying for a MSC-EV pro-duction license in near future.

The program of the GSCN annual conference covered the whole the-

matic spectrum of the working groups from cancer stem cells to pluripotency.

Birte Baudis (Institute for Neurophysiolo-gy, Cologne) reported in the session “Stem cells in

regenerative therapies” on the immunologic properties of murine embryonic stem cell (ESC)-derived cardiomyocytes (CMs) in immunocompetent mice mismatched for major (MHC) or minor histocompatibility antigens (mHAg). She found that eight weeks after transplantation the survival of ESC-CMs transplanted under the kidney capsule was comparable in both experimental groups and in immu-nodeficient mice. Surprisingly, the immunization of mice with the mHAg expressed by ESC-CMs did not reduce the CM survival although it induced mHAg-specific cytotoxic T cells (CTLs) and caused rejection of control cancer cells

that expressed the same mHAg. In vitro analyses demonstrated that this apparent “immunolog-

ical privilege” of ESC-CMs in vivo could be due to very low levels of MHC molecules

expressed on the surface of ESC-CMs and their reduced susceptibility to lysis by CTLs. Aline Bozec (Erlangen, Germany) reported in the session “Stem cells and aging, genome stability and epigenet-

ics” on how a high fat diet changes the hematopoietic stem cell (HSC) bone mar-

row niche. Mechanistically, diet-induced changes of the intestinal microbiota, particu-

larly gram+ bacteria, induced a switch of mesen-chymal stem cells from osteoblasts to adipocytes, which consequently alter HSC differentiation.

4TH ANNUAL CONFERENCE OF THE GSCN

Not all the lectures in Hannover were dedicated to basic science – many focused on legal, ethical and philosophi-cal aspects of stem cell research. A special symposium

gave researchers the opportunity to discuss how artificially generated “totipotent”

cells should be viewed in the context of current definitions of embryos

in German law. “The symposium on ‘Totipotent non-embryos and non-totipotent embryos’ certain-ly delivered on its provocative title,“ said Martin Heyer from

the Institute of Science and Eth-ics at the University of Bonn. „The

exciting issues involved in the hotly debated topic of totipotency were dis-

cussed in depth and at a high level by the speakers and the audience. The fact that the event was part of the GSCN Annual Conference made it particularly successful.”

Following a lecture by Thomas Eschenhagen (UKE, Ham-burg) on heart muscle cells in disease modeling, “Engineered human heart muscles for disease modeling and cardiac re-pair” (see above), the central Presidential Symposium pre-sented the winners of the GSCN Awards. The winner of the Young Investigator Award 2016 Leo Kurian (University of Cologne) spoke about his lab’s work in the field of develop-mental biology on non-coding (Inc) RNAs and their signifi-cance in inducing the embryonic development of the heart. “I am delighted to be recognized by the German Stem Cell

Net-work. I would like to thank my lab, to whom the credit really be-longs for the work we do and to GSCN for the award. This was my first GSCN meeting and in my opinion this is a great forum to learn about national research efforts and a great platform for networking. I am particularly impressed with the diversity of the groups and excited about the excellent science presented,” said Leo Ku-rian on receiving the GSCN award.

The GSCN Female Award 2016 went to Claudia Waskow (TU Dresden). “I am delighted about the award and regard it as an exceptional distinction for the work that my team and I have been able to conduct in the last few years,” said Claudia Waskow about the award that recognizes her out-standing scientific achievements. She held a lecture enti-tled “Generation and regeneration of human and murine hematopoietic stem cells”.

The GSCN Publication of the Year 2016 award went to Guangqi Song, Martin Pacher, Michael Ott and Amar Deep Sharma of the REBIRTH Center and the TWINCORE Center of the Hannover Medical School (MHH) for their publica-

qi Song held a lecture with the same title as the publication at the GSCN conference. Their

article impressively demonstrates how Shinya Yamanaka’s work on reprogramming has given rise

to a technology that now enables the direct conversion of a cell of one type into other cell types in the organism. These approaches could revolutionize the treatment of many severe diseases in the future.

Both poster sessions triggered lively discussion and de-bate. A total of 150 posters were presented in sections cor-responding to the different working groups. The informa-tion displayed was studied with great interest. The poster awards provided by GSCN member company Peptrotech, went to:

• Antje Appelt-Menzel, University of Würzburg, TERM: “Establish-ment of a human blood-brain barrier co-culture model based on human multipotent and pluripotent stem cells mimick-ing the neurovascular unit”

4TH ANNUAL CONFERENCE OF THE GSCN

The scientific program of the conference was rounded off with a REBIRTH session addressing the whole range of ethical and legal aspects of stem cell research from basic research to heart development and the treatment of heart disease, with presentations by Nils Hoppe, Leibniz Univer-sität Hannover, and Kai Wollert, Thomas Thum and Robert Zweigerdt from the Hannover Medical School. The GSCN

conference prides itself on further improv-ing its format and its program of events

every year. The Program Committee thus followed the call to offer even

more “meet the expert” tables, where small groups are given the opportunity to fire questions at “experts” during the lunch breaks. This year’s experts were

Ingo Roeder (TU Dresden), Hans Schöler (MPI Münster), Ana Mar-

tin-Vilalba (DKFZ Heidelberg), Mari-sa Karow (LMU Munich), Henner Farin

(Goethe University Frankfurt) and Ina Gruh (REBIRTH, Hannover). “We had a very interesting dis-cussion with Hans Schöler,” said conference partici-pant Sebastian Diecke. “We didn’t just talk about stem cell research but also about career-related issues, such as how best to acquire funding. It was a great opportunity to ask questions di-rectly and get really helpful answers.”

A new component of the conference was the Technology Exchange Workshop where researchers had the chance to present innovative technologies to in-dustry. Selected projects were briefly presented and their potential for industrial application was then discussed. “It

was exciting because we had some great projects and good discussions. Over time and once the event has become more widely known, this could develop into a real technol-ogy transfer exchange,” said Daniel Besser, who initiated the workshop. “We plan to work on developing it further.”

A range of strategic issues was also addressed and dis-cussed at length during the conference in Hannover. Topics included the promotion of young scientists, clinical trials,

regulatory issues and technologies in stem cell research. Alongside an excellent session on organoids by the

working group “Technologies in stem cell re-search”, the session on “Clinical trials and reg-ulatory affairs” proved to be one of the high-lights of the conference. It consisted of three lectures on research translation. Felipe Pros-

per from the University Hospital Navarra, Pam-plona, spoke about European funding for transla-

tion relating to therapies using stem cell derivatives, using his university as an example. This was followed by a lecture by Arnd Hoeveler from the European Commission, and then by Aliki Nichogiannopoulou from the European

“We will develop the Tech-Transfer-

Exchange“

The German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ), located in Heidelberg, is a member of the Helmholtz- Association and is the largest biomedical research institute in Germany. At the DKFZ, more than 1,000 scientists work together in order to develop novel strategies aimed at improving the prevention, diagno-sis and treatment of cancer. Several research laboratories investigate normal and cancer stem cells (CSCs) as well as their respective niches. The goal is to develop strategies to monitor and

target CSCs in primary cancers and metastasis. Together with the Dietmar Hopp Foundation, the DKFZ is a shareholder of HI-STEM, the nonprofit Heidelberg Stem Cell Institute and organizes the biannual Heinrich-Behr-Conference on „Stem Cells and Cancer“, which attracts international experts in the field. With the Heidelberg University Clinic, the DKFZ has established the National Center for Tumor Diseases (NCT), to clinically translate innovative basic cancer and stem cell research discoveries into clinical therapies.

Patent Office, Munich on the patenting of stem cell-based inventions. The discussion, which continued well into the following break and could have carried on a lot longer, gener-

ated much poten-tial for discussion

at future GSCN con-ferences.

A special highlight of the Han-nover conference was the GSCN Net-

working Evening – which was held at the zoo! In pleas-ant summer temperatures, the conference participants strolled through the otherwise deserted zoo, admired the wolves and monkeys, and then, with a welcome drink in hand, enjoyed watching the feeding session of two polar bears. In a setting reminiscent of a Canadian logging town, the participants observed the seals and penguins, ate ham-

burgers from the barbecue and enjoyed the lush summer evening far away from the lecture halls. There was ample opportunity for networking fun, rounded off by dancing under the full moon and a nocturnal walk through magical

settings with flares leading the way back through the zoo. It’s no surprise then that the evening was given a

straight “Excellent” rating in the online evalua-tion. The get-together on the first evening of the conference was also a lively and relaxed occasion with good food and plenty of good discussion on a pleasant summer’s evening.

The final event of the GSCN conferences is tra-ditionally a public event in the hosting city. On the

Wednesday evening in Hannover, chief physicians Michael Manns and Axel Haverich together with Ulrich Martin, Tobias Cantz and lawyer Nils Hoppe – all from REBIRTH and the MHH – made up the panel hosted by Stefanie Seltmann, DKFZ press of-ficer, to speak about the oppor-tunities and the future of stem cell research. In the unusual setting of a former newspa-per hall of the Hannoversche Allgemeine Zeitung, the GSCN showed its new movie por-traits on the work of the pan-el participants. The portraits on Michael Manns and Tobias Cantz, as well as Ulrich Martin and Nils Hoppe are available in English and German on the GSCN website.

Research at the Max Planck Institute for Molecu-lar Genetics (MPIMG) concentrates on genome analysis of man and other organisms. It is the overall goal of all MPIMG’s groups to gain new insights into the development of diseases on a molecular level, thus contributing to the develop-ment of cause-related new medical treatments. Work at the MPIMG is characterized by a genome-wide approach to scientific questions. In this context, the very close connection bet-ween experimental and computational methods has become a major feature of all departments

and research groups at the institute in recent years. MPIMG researchers are interested in questions of epigenetic regulation and work on a better under-standing of gene regulation networks for tissue formation and homeostasis, as their dysfunction my result in numerous diseases. In this context, stem cell research is gaining increasing importance.

RESEARCH FUNDING

While public funding of stem cell research is increasing steadily in the United Kingdom, Sweden, Japan and the US, stem cell researchers here in Germany have been faced with steadily dwindling resources in the last few years both from the Federal Ministry of Education and Research (BMBF) and the German Research Foundation (DFG). These are the findings of a German Stem Cell Network (GSCN) white paper1 published in September 2016. The paper concludes that Germany’s research and innovation policy needs to give greater priority to stem cell research and provide funding for a balanced mix of basic and applied research.

Germany is commonly regarded to be one of the lead-ing countries worldwide in stem cell research. But are public funding schemes adequately supporting

fulfillment of this scientific potential? To answer this ques-tion, the GSCN conducted a survey of the national and inter-national research landscape. As well as gathering data and facts on research policy in Germany, the UK, the US, Sweden and Japan, the study also interviewed eight German and international stem cell experts to pinpoint the strengths, weaknesses, risks and opportunities of public research funding in the different countries.

Tangible decline in funding in Germany

The paper’s report on public funding in stem cell research in Germany presents a sobering picture. On the one hand, the federal government has visibly invested in health re-search with a strong focus on national centers and clusters of excellence, and non-university research has been boost-ed by higher levels of institutional funding. On the other hand, federal funding schemes specifically geared towards individual stem cell projects and their transregional inte-gration has declined steadily in the last few years.Between 2009 and 2014, the BMBF spent around €167 mil-lion on funding stem cell research and regenerative medi-cine. The funds went to a total of 341 individual and joint projects as well as large-scale structural projects, most no-tably the translation centers for regenerative medicine in Leipzig, Berlin and Rostock. This corresponds to an average annual funding of €27.7 million for projects from the BMBF. Calculations of average annual values of project budgets based on the duration of funding for the respective projects reveal a clear downward trend since 2011. These figures do not include the exten-sive institutional federal funding for the biomedical insti-

tutes of Germany’s four large research associations (Max Planck, Leibniz, Fraunhofer, Helmholtz) or the budgets of the German Health Research Centers. The figures clearly show that stem cell research as a cross-cutting discipline has receded into the background as far as public funding policy is concerned. New calls for proposals have been few and far between since 2010. The only new BMBF funding initiative relevant to biomedical scientists was the 2015 initiative for “innovative stem cell technologies for individualized medicine” (see “Research” section for more information).

The DFG is the second biggest funding body for basic stem cell research in Germany after the BMBF, providing an av-erage of €22.5 million in funding per year for approved stem cell research projects. This annual average increases to €36 million if one includes the two DFG centers with a clear focus on stem cell and regenerative medicine in Dres-den (CRTD) and Hannover (REBIRTH). Funding was at its lowest in 2014, leaving university groups, whose projects frequently rely heavily on DFG funding, with ever dwin-dling resources.

The conclusion drawn by the authors of the white paper in their analy-sis of the state of public funding in Germany is that the German government was quick to focus on translation in health re-search by investing primarily in translation infrastructure, such as the translation centers for regenerative medicine that have been set up in Berlin, Leip-zig and Rostock since 2006 and are concerned mainly with tissue engi-neering and adult stem cells. The high volume of funding tied up in these initia-tives meant that the system was subsequently not in a position to response flexibly to ground-breaking developments in stem cell research such as cell reprogramming.

According to the report, the restrictive legal environment for stem cell research in Germany has been another hurdle contributing to the delay in pluripotent stem cell research. Despite these obstacles, however, there are still grounds for optimism. A solid base of expertise has been estab-lished in both basic and biomedical stem cell research disciplines in Germany that has the potential to support successful translation from bench-to-bedside for many years to come.

RESEARCH FUNDING

Stem cells as an engine of innovation in the US, UK, Sweden and Japan

Research policy in the US, Japan, the United Kingdom and Sweden takes a completely different approach. “Stem cell research and regenerative medicine are firmly established as strategic priorities in the research and economic policy of these countries and are regarded as drivers of innovation,” says the GSCN white paper. Stem cell research in these countries benefits from far more diverse and large-scale funding programs estab-lished specifically for this field. The United Kingdom, for example, has set up substantial funding schemes since

2012 including the UK Regenerative Med-icine Programme (UKRMP) and the Cell

Therapy Catapult, designed to inject new momentum along the entire chain of innovation in regenerative medi-cine and cell therapy. The country in-vests more than €150 million a year in stem cell research. Sweden selected

stem cell research and regenerative medicine as one its 24 research areas

of highest strategic importance in 2008. It has set up stem cell centers at universities,

most notably at the Karolinska Institute in Stockholm, but also in Uppsala and Lund,

Our main research focus is the development of human tissue and organ models that can be used as alternative test systems instead of animal research and that allow the establishment of innovative implant structures used for future therapeutic strategies. Our models are based on vascularized carrier structures (e.g. BioVaSc®) that are reseeded with cell lines, primary cells or iPSC-derived cell types. Application of primary cells or iPSC-derived cell progenies potentially enables the establishment of functional implants that minimize the risk of immune rejections and contribute to the activation of important biologi-cal mechanisms regulating natural regeneration.

Culturing of our tissue and organ models in specific bioreactors ensure cellular functionality in vitro by mimicking in vivo-like microenvironmental condi-tions. Besides the barrier systems skin, intestine, trachea and blood-brain barrier, we also established tumor models of diverse organs.

As revealed by an analysis of the EU Directorate-General Research and In-novation for the GSCN white paper, UK stem cell researchers acquired the highest proportion of FP7 health research funding (€144 million), followed by Germany with €141 million. Sweden, with a population only around a tenth of that of Germany (9.8 million com-pared to 81.2 million), managed to secure €43 million of EU funding.

In Japan, where iPS technology was first scientifically documented in 2006,

the further development of the field has received a large volume of dedicated state

support since 2008. iPS cells are regarded as a flagship technology in health research and considered a

powerful economic driver, not least because of the many key patents granted to Japanese researchers. Annual fund-ing in Japan for iPS cell research alone amounts to around €90 million.

The four countries exam-ined in the study all have a more liberal legal en-vironment and invest in research across the entire range of stem cell types. They are thus the first coun-tries where clinical trials are going ahead for therapies based on pluripotent stem cells.

Making better use of Germany’s potential

Based on their comparative analysis of the funding situ-ation in the different countries, the authors of the GSCN white paper arrived at the following recommendations for political decision-makers and funding bodies:• Stem cell research as a cross-cutting discipline needs to

move back up the research and innovation policy agen-da.

• In view of the increasing volume of public funding pro-vided in other countries, Germany should draw level and invest more in stem cell research funding, also in the long term.

• Funding needs to achieve a balanced mix of solid basic research and translational research. This combination is particularly well established in Germany and should continue to be closely linked in the future.

• Funding formats to bridge gaps along the translation and value chain best address the needs of the diverse re-search landscape. Alongside centers and clusters, trans-regional and interdisciplinary research alliances are the ideal way of increasing the connectivity of the stem cell research community.

And then, of course, there’s the US. The National Institutes of Health (NIH) alone have lately been spending more than $1.5 billion (€1.37 billion) per year on stem cell research. The wide range of funding schemes, strong capital base of universities and substantial investments made by the indi-vidual federal states have created an extremely favorable climate for stem cell research and regenerative medicine in the US over the last few years. In New York State alone, annual investments in stem cell research exceed the DFG’s total annual budget for basic stem cell research projects for the whole of Germany.

The Berlin-Brandenburg Center for Regenera-tive Therapies (BCRT) is an interdisciplinary translational center with the goal of enhancing endogenous regeneration by cells, biomaterials, and factors which can be used to develop and implement innovative therapies and products. At the BCRT clinicians and researchers are working closely together on a personalized medicine that depends on the early recognition of patients‘ individual healing potential. The primary focus of the BCRT is on diseases of the immune system, the musculoskeletal system,

the cardiovascular system and the kidney for which currently only unsatisfactory treatment options are available. Early cooperation with industry, health insurers and regulatory authorities as well as other external partners boosts the chances of exploiting new methods and provides access to flexible finan-cing options.

RESEARCH AND APPLICATION

Future perspectives in stem cell research

A mix of powerful technologies has turned stem cells into a key tool for the life sciences both in basic research and clinical application. The huge diversity of innovation poten-tial found in German labs is reflected in the joint research projects backed by the new BMBF funding initiative for stem cell technology. Collaboration between academic research and the pharmaceutical industry is also picking up tangibly, particularly for cell-based disease modeling and drug screening. This article presents a selection of new national and international projects and centers that are set to shape stem cell research over the coming years.

About ten years ago, Shinya Yamanaka revolution-ized biomedical research with the discovery of hu-man induced pluripotent stem cells (iPS cells). The

technology was quickly adopted in German labs, too, and was soon followed by further developments such as ge-nome editing with designer nucleases including TALENs and CRISPR-Cas9. The ability to create three-dimensional mini-organs called organoids and the mass production of differentiated cells have opened new horizons. In combina-tion with new imaging techniques and bioinformatic analy-sis tools, research has advanced into areas that would have been unthinkable just a few years ago.

New joint research projects for innovative stem cell technology

The many different joint research projects supported by the new funding initiative of the Federal Ministry of Edu-cation and Research (BMBF) demonstrate the huge inno-vation potential of these procedures. The BMBF funding initiative “Innovative stem cell technologies in individual-ized medicine” established in 2015 is the first initiative for many years targeted specifically at stem cell researchers in Germany. The coordinating agency for the project, Germa-ny’s aeronautics and space research center DLR, reported that the response was huge, with more than 70 research alliances submitting project proposals. Thirteen projects have been selected and will be funded with a total of €21 million up to 2020. A research alliance consists of two to five partners. All the projects funded aim to develop better cell-based disease models for research and test systems for drug screening.

Improving cryopreservation

The research alliance Stabil-Ice consists of a team from the Fraunhofer Institute for Biomedical Engineering (IBMT) in Sulzbach, south-west Germany, and neuroscientists from the University of Erlangen-Nuremberg who are aiming to make a significant improvement in the cryopreservation of iPS cells and the neuronal cells derived from them.

The only way to preserve live cells for long periods is to store them at extremely low temperatures, normally pro-vided by liquid nitrogen. This involves enzymatic removal of the cells from the supportive growth surface and freez-ing them as individual cell suspensions with cyroprotect-ants. However, this is always accompanied by the formation of ice crystals. “A considerable amount of cell function and even whole cells are lost in this process,” says Ina Meiser, head of the IBMT working group Cryobiotechnology.

To get around this problem, the team of researchers is working on developing an innovative disposable plastic container in which all the necessary cell culture steps can be carried out and the cells cryopreserved without ice crys-tal formation. According to Meiser, this is especially useful for neuronal cells with their delicate dendrites that depend on adherent growth. Another advantage is that, after thaw-ing, there is no need for the previously required recovery and cultivation phases, meaning that the cells are imme-diately available for experiments. “The iPS cells remain in the disposable container throughout, and can grow on the cell-specific surfaces and differentiate there as well,” says Meiser.

34 Stem Cell Research: Potentials & Perspectives

RESEARCH AND APPLICATION

Differentiation strategies for different types of neuronal cells are delivered by project partner Beate Winner from the University Hospital of Erlangen. Winner’s working group specializes in iPS cells derived from the fibroblasts of Parkinson’s patients.

Meiser reports that the first results from the ready-to-use system are already very promising. She is convinced that the stable ice system can make an important contribution to providing a supply of human nerve cells cost-efficiently and with a consistent level of quality. Demand for standard-ized cell material is especially high in the fields of drug de-velopment and testing, particularly for innovative therapies to treat neurodegenerative diseases. The BMBF is funding the project until the end of 2019 with around €950,000.

Kidney organ-on-a-chip for drug tests

Combining modern microsystem technology with orga-noids derived from iPS cells is the objective of the research alliance micro-iPS-Profiler. The four partners of the alli-ance are from Jena, Berlin and Heidelberg. They started work in November last year to develop a microfluidic chip on which an organ can be replicated and modeled in miniature format. The technology platform is being devel-oped by a team headed by Holger Becker from Microflu-idic ChipShop GmbH in Jena. For now, the researchers are focusing on the kidney for their organ chip. “The kidney is made up of many different cell types that we can already produce from pluripotent stem cells,” says Andreas Kurtz from Berlin Charité University Hospital. His team will deliver cell material from patients with kidney diseases. The challenge is to combine the cells into a functioning three-dimensional mini-organ, called an organoid. The

targeted outcome of the project is a multi-organ chip in which kidney and liver organoids are interconnected. The system could be used for high-throughput screening and testing of drugs. The BMBF is funding the project with €2.5 million.

Meanwhile, the project partners in the PancChip alliance will be focusing on producing a pancreas chip for diabe-tes research. The team, headed by Heiko Lickert from the Helmholtz-Center in Munich and Matthias Meier from Frei-burg will derive insulin-producing beta cells from stem cells and use them to construct the pancreas organoids. These three-dimensional model systems will be used by biomedical researchers to investigate the development of diabetes and possible replacement therapies in miniature format (funding: €1.5 million).

Bavarian Research Network Induced Pluripotent Stem Cells (ForIPS)Uniklinik Erlangen

ForIPS aims to establish the iPS technology and to use iPS cell derived neural cells as models to analyze the pathogenesis of Parkinson’s disease (PD). Scientists of ForIPS re-program skin cells from PD patients and healthy control subjects, and differentiate those patient specific iPS cells into neural cells. As these neural cells constitute very specific cellular models researchers hope to decipher the underlying pathogenic mechanisms of PD.

The core project is the heart of the Bavarian Research Network ForIPS. This platform provides human iPSCs and neuronal derivates from Parkin-son patients and healthy controls. Scientifically, the core project aims to establish complementary non-integrating reprogramming strategies. Another aim of the core project is to establish a biobank for human iPSCs in Bavaria.Setting up this efficient platform will be a starting point for advanced investigation of other brain diseases or disorders of other organs.

Institute of Reconstructive NeurobiologyFrom disease modeling to stem cell therapies

Translation: connecting academic research with the pharmaceutical industry

Stem cell-based drug screening and drug development are becoming increasingly important in pharmaceutical research. The stem cell technology center CARE is being set up in Munich to facilitate progress in this field. CARE, the Center for Advanced Regenerative Engineering, will

serve as a translation center that combines modern stem cell technology with pharma-

ceutical research. It will use iPS cells and in vitro disease models for high-through-put drug testing. The State of Bavaria is providing €25 million of start-up financ-ing for the center. The CARE concept was initiated by stem cell researcher Hans Schöler, head of the Max Planck Institute for Molecular Biomedicine in Münster. In his presentation of CARE to politicians,

business representatives and scientists in April 2016, he said that the institute

would employ around 60 members of staff. The center will initially focus on neurode-

generative, cardiovascular and rare diseases. Not just large, but also small and medium-sized

enterprises operating in drug research will have the opportunity to actively engage in the center.

CARE is to be built on the biotech campus in Mar-tinsried.

The designated CARE managing director, Ulrich Gerth, has informed us that the contractual framework conditions are in the final agreement stage and the legal corporate structures are being prepared. The Dortmund-based Lead Discovery Center (LDC) is already an important partner of CARE. LDC is a translation company founded by Max Planck Innovation in 2008 and will be providing its exper-tise in the testing and validation of small molecules and chemical substances. The CARE coordinators in Munich are currently still exploring whether the LDC concept can be applied to the development and validation of biophar-maceutical agents. Ph

New analgesic drugs to treat neuropathic pain

An alliance of academic research and industry started up last year in North-Rhine Westphalia to investigate stem cell-based approaches to research on analgesic drugs. The consortium, called NeuRoWeg, is led by pharmaceutical company Grünenthal, and successfully secured a grant of €1.5 million in the first round of the leading market competition LifeSciences.NRW. The other partners in the interdisciplinary consortium are the Institute of Recon-structive Neurobiology at the University of Bonn, trans-lation company LIFE & BRAIN GmbH and the University Hospital Cologne.

The research network will be investigating neuropathic pain. This pain is caused by disorders to the peripheral nervous system as a result of accident or severe disease. Using the example of diabetes-induced neuropathic pain, the NeuRoWeg researchers want to establish a stem cell-based system for basic research on pain and industrial drug research. Nerve cells of the pain system can be de-rived in the lab using iPS technology. The expertise in

the generation of pluripotent stem cells and their differ-entiation will be supplied by the research team from the Institute for Reconstructive Neurobiology headed by Oli-ver Brüstle. LIFE & BRAIN GmbH will be in charge of the standardized and automated mass production of cells and the development of informative test systems.

There was more good news in store for the Bonn-based stem cell researchers in December 2016. In the second round of the leading market competition LifeSciences.NRW, the consortium StemCellFactory III was selected for funding, thus securing the financing for the third phase of this flagship project. Over the last few years, a robotics line has been constructed on the premises of LIFE & BRAIN GmbH, with the support of the federal state of North-Rhine Westphalia, where iPS cells can be produced and matured into neural cells in a fully auto-mated process. In the new round of funding, the research partners want to investigate standardized and integrat-ed procedures for the individualized stem cell-based prediction of drug efficiency using reprogrammed blood cells.

Spotlight on ethical and legal aspects

The technological potential of modern stem cell research raises new ethical and legal issues. What changes will the production of artificial germline cells using iPS technology bring to reproductive medicine? Can the developments coming from stem cell labs be patented? What are the problems involved in the clinical application of iPS cells? Under its funding priority “Ethical, Legal and Social As-pects of Modern Life Sciences and Biotechnology” (ELSA), the BMBF is funding six interdisciplinary research projects on the topic of stem cells.

REGENERATIVE MEDICINE

Testing clinical maturity

While stem cell therapies have become standard in the treatment of leukemia, it will take a good few years until pluripotent stem cells can be used as a resource in regen-erative medicine. The first clinical trials with replacement tissue developed from pluripotent stem cells have started around the world. But how safe and how effective are these new therapies? The stem cell community wants to har-monize standards for producing clinical-grade cells from pluripotent stem cells and is testing the quality of the cells to optimize their clinical application. Systematic online cat-alogs such as hPSCreg are an important resource here. The GSCN working group Clinical Trials brings together stem cell experts and regulatory authorities to address important issues in good time.

While stem cells have become a fixed component of drug research and drug development, the clinical application of cell-based therapies is still

largely confined to the experimental stage. Cell-based ther-apies are highly complex and generally tailored to individ-ual patients. They are also subject to stringent regulatory requirements and manufacturing standards. As with other drugs, stem cell-based therapies have to be tested for their safety and effectiveness in clinical trials (cf. GSCN Annual Magazine 2015/2016). The register of clinical trials clin-icaltrials.gov has registered more than 2,000 stem cell-based studies, the majority of which are related to hemato-poietic stem cells and mesenchymal stem cells (MSCs).

A new generation of cell replacement therapies is emerging across the world and also throughout Europe. A number of clinical trials of preparations based on human embryon-ic stem cells (ES cells) and induced pluripotent stem cells (iPS cells) are already underway. “At present, 30 clinical trials are taking place around the world based on pluri-potent stem cells, mostly ES cells,” says Andreas Kurtz of the Berlin-Brandenburg Center for Regenerative Therapies (BCRT) at the Charité. He is one of the initiators of the GSCN’s strategic working group Clinical Trials and Regulatory Affairs.

Bayer banking on cell therapies

Just how important the latest generation of regenerative therapies is in the eyes of the big pharmaceutical companies became clear in December last year when the Bay-er group created a stir by founding the start-up BlueRock Therapeutics. Together with venture capital fund Versant Ven-ture, Bayer is investing the gigantic sum of $225 million in the start-up to develop highly efficient therapies based on iPS cells. BlueRock Therapeutics will initially focus on

cell replacement therapies for heart tissue that has been damaged by heart attacks and replacement therapies with dopamine-producing neurons for Parkinson’s patients. The R&D work is, however, taking place in partnerships outside of Germany – in Toronto, New York and Boston. “Stem cell-based therapy developments in Germany have not yet reached sufficient maturity to be available as part-ners for these kinds of initiatives from the pharmaceutical industry,” says Daniel Besser from the GSCN Central Office. “We need to strengthen structures here in the country to facilitate the translation of our excellent basic research into application.”

Stem cell register hPSCReg has its sights on clinical application

The pluripotent cell lines used by the Bayer start-up may also one day be recorded in the stem cell register hPSCreg.eu.

Charité researcher Andreas Kurtz is one of the coordinators of hPSCreg, further partners are the Barcelona stem cell bank at CMR[B], the UK Stem Cell Bank near London and the Chinese Academy of Sciences. The online information portal was launched in 2007 with a grant from the Euro-pean Commission to create transparency in the use by re-search labs of the controversial ES cells. The unprecedented success of iPS technology in the production of pluripotent stem cells has caused a rapid increase in the number of en-

tries in the register. The portal has expand-ed its range of functions accordingly and subjects the registered cells to in-depth testing according to clearly defined stand-ards. “We are now the leading global register for pluripotent stem cell lines,” says Kurtz. In February 2017, the register included 690 ES cell lines and 452 iPS cell lines. The records for each cell line include information on their origin, their molecular biological profile, their scope of application and, of course, their storage location.

The European Commission plans to con-tinue funding the hPSCreg at least for

the next four years. “We will now focus in particular on cell lines

that are suitable for clinical application,” says Kurtz. The

most important task now is to further develop and harmonize the required quality standards. “We want to become an in-ternational platform for harmonization,” says

Kurtz. Plans are also afoot for hPSCreg to record and

present all future clinical trials that are conducted

worldwide on the basis of pluripotent stem cells. Kurtz

and his five-strong bioinformatics team have also developed minimum

informationstandards together with international partners from Japan, the United Kingdom and the United States. These are uniform data formats designed to help improve information exchange between cell banks and registers.

iPS cell banks linking up

In Japan, a study involving the world’s first iPS cell-based therapy to treat a retinal disease. has been resumed. The trial had been put on hold as a precautionary measure after genetic mutations were discovered in the cells to be trans-planted to a patient suffering from macular degeneration.

The Fraunhofer IME conducts research in applied life sciences from a molecular level to entire ecosystems. Our interdisciplinary organization and laboratories with most recent equipment including GMP facilities and complex facilities for environmental simulations allow a wide spect-rum of research and development services. IME’s overarching goal is the development and use of novel technologies for diagnosis and therapy of human and animal disease as well as protection of crop plants and food supplies. IME has close ties in terms of personnel and areas of work with

the Institute of Molecular Biotechnology of the RWTH Aachen University, the Department of Biology and Biotechnology of Plants of the University Münster, the Department of Applied Entomology of the University Gießen and the Institute for Clinical Pharmacology of the Goethe University Frankfurt/Main.

REGENERATIVE MEDICINE

The study team led by Masayo Taka-hashi from Kobe adapted their strategy and are now using allogeneic cells in-

stead. These cells are derived not from the patients themselves but from do-

nors whose cells are genetically flawless and as immunologically compatible with

the patient as possible.

The concept works in the same way as the im-munological donor selection for stem cell trans-

plantations. The cells used are ideally derived from persons with blood type 0 and who are ho-

mozygous for a characteristic tissue-compatibility an-tigen pattern – so-called haplotypes of the HLA system.

Many experts regard the storage of such immune-matched iPS cells in biobanks as key for the regenerative medicine

of the future. However, only a globally connected initiative will be able to ensure that suitable cells can be found for a given patient. The Global Al-liance for iPSC Therapy (GAiT) represents a step in this direction. This collaborative project of various institutes including the New York Stem Cell Foundation and UK’s Cell Therapy Cat-apult aims to set up iPS haplo banks with cells that are quality assured as clinical grade. Here too, Andreas Kurtz and his Berlin bioinformatics team are making an im-portant contribution: “We are building a database for the GAiT to record the cell lines. We want to set standards here and push for their application. And in the medium term we hope to become a resource for the regulatory authorities, too.”

As a spin-off from the Medical Faculty, Heinrich-Heine- University Düsseldorf and the Max Planck Institute for Molecular Biomedicine Münster, RheinCell Therapeutics company focuses on the GMP compliant production of human induced, pluripotent stem cells (iPSC) from HLA-homozygous cord blood stem cells. GMP compliant episo-mal reprogramming technologies are employed to develop a mastercellbank of HLA-homozygous iPSC, which can be used as ATM-products for a variety of allogeneic off the shelf transplantations, e.g. retina pigment epithelial cells for the treatment of macula degeneration or CAR-T/NK-cells for the treatment of solid tumors.

REGENERATIVE MEDICINE

Institute for Stem Cell Research and Regenerative Medicine (ISRM)Regenerative Medicine at a glance

At the institute for stem cell research and regenerative medicine we adopt a systems biology approach to better understand normal development (hepatogenesis, nephrogenesis and neurogenesis), ageing and disease me-chanisms (Steatosis/Non Alcoholic Fatty Liver Disease, Alzheimer’s Disease, Nijmegen Breakage Syndrome and Crigler-Najjar syndrome). We are actively involved in the EU/FP7 funded project AgedBrainSYSBIO (http://agedbrainsysbio.eu/) where we study mechanisms underlying late onset Alzheimer’s Disease (LOAD).Mechanisms underlying the induction and maintenance of pluripotency and the derivation of patient speci-

fic induced pluripotent stem cells (iPSCs) differenti-ated into relevant cells types (2D and 3D) are core to these efforts. Omics-based datasets (transcriptome, proteome, methylome and secretome) Bioinforma-tics, mathematically modeling, pathway reconst-ruction and data management are central to our research.

Centralized service units with clinical relevance

Infrastructure is being built up in Germany to pave the way for pluripotent stem cells from bench to bedside. In the last few years, several large research institutes in Ger-many have set up centralized service units for pluripotent stem research, known as stem cell core facilities (cf. GSCN Annual Magazine 2014/2015). With the assistance of the GSCN and the Berlin Institute of Health (BIH), the PluriCore network was set up two years ago. This network is a joint initiative of the stem cell core facilities of Aachen, Berlin, Bonn, Dresden, Erlangen, Freiburg, Göttingen, Hamburg, Hannover, Kiel, Münster and Munich that aims to establish common standards for experiments and to promote the sharing of experience and material. The concept is working

well and has also attracted attention abroad. The stem cell core facility in the Dutch city of Leiden has also recently joined the network.

The contacts created through the network have already proven useful for the joint acquisition of third party fund-ing. The Federal Ministry of Education and Research is funding a three-year joint project called iPStemRNA that has partners from Munich, Berlin, Bergisch Gladbach and Dresden. The project is dedicated to developing iPS cell lines that meet the stringent requirements of good man-ufacturing practice, or GMP. This is a prerequisite for their use in future cellular therapies. Furthermore, these iPS cell lines are to provide an immune-compatible match for the majority of the population at the level of the major tis-sue-compatibility antigens (HLA).

The industry partner for the project is Miltenyi Bi-otec GmbH from Bergisch Gladbach. The BMBF is funding the joint research project with just under €1.5 million.

The GSCN working group Clinical Trials collabo-rates closely with the Paul Ehrlich Institute (PEI),

Germany’s federal licensing authority for biomedi-cal drugs. One example of this collaboration is a joint

workshop that was held on 10 Nov. 2016 in Langen. As it is hoped that clinical trials with iPS cell-based preparations will be starting in the next few years in Germany as well, the GSCN wants to elaborate joint positions with the PEI for next-generation cellular therapies and regenerative med-icine. The joint initiative will also be addressing further topics such as mesenchymal stem cells, the ethical aspects of licensing, and the manufacturing permits of the federal states. Text: Philipp Graf

CAREER DEVELOPMENT

Well-equipped for a career

A wide range of professional opportunities both in science and in private enterprise is open to stem cell research-ers once they have obtained their doctorate or post-doc qualification. The GSCN Career Development group aims to help young scientists find the right career path by offering special sessions at the GSCN annual conferences as well as multi-day workshops. The working group also places a special focus on careers for women in stem cell research and is currently considering setting up a support scheme for young families.

Why are stem cell researchers in such high demand on the labor market? For Insa Schröder, a re-searcher based in Darmstadt, one reason imme-

diately springs to mind. “The special thing about us is that we are used to working in highly interdisciplinary teams,” she says, “but we need to communicate this advantage more clearly to industry.” Schröder, a certified food chemist, her-self embodies this diversity: after several stints working in toxicological and biomedical research in Berlin, Washing-ton and Halle/Leipzig, she took up a position at the Helm-holtz center for heavy-ion research (the GSI Helmholtzzen-trum für Schwerionenforschung) in Darmstadt. Here she is conducting research into the impact of radiotherapy on tissue regeneration. “There are all kinds of different career paths to choose from, which makes things exciting but not always easy,” says Schröder. “We want to help young scien-tists actively shape their careers.”

The strengths of stem cell researchers

Schröder initiated the GSCN strategic working group on Ca-reer Development together with Hartmut Geiger, head of the Institute of Molecular Medicine at Ulm University. For Geiger, a researcher on aging processes in stem cells, it is his passion for his field of research that motivates him to engage in career development work: “If we want to attract more people to this fascinating field of research we need to offer mentoring services, and I’m happy to take an active role here.” He points out that the interdisciplinary mindset of stem cell researchers is not their only advantage. “Stem cell research often tends to be extremely complex. It takes special skills to truly understand the topics involved.” A fur-ther strength of the research area is its translational com-ponent, i.e. the application-oriented connection to clinical work and pharmaceutical research. “This makes stem cell researchers very innovative and flexibly deployable,” says Geiger.

The German Stem Cell Network’s career development ac-tivities are based on three pillars: The GSCN annual confer-

ence, with around 400 participants last year, has become a highlight for young stem cell researchers from the bachelor to senior post-doc level. Geiger believes this annual meet-ing is an ideal platform for young scientists here in Germa-ny. “There’s lots of interaction at the conference and it of-fers all kinds of networking opportunities. This gives young researchers a good feel for their position in the field and the options ahead.”

For the GSCN annual conferences, Schröder and Geiger organize a special session on career development. “We don’t just have people talking about their career in aca-demic research or in the pharmaceutical industry,” says Insa Schröder. It is important to her that the guest speak-ers also always present alternative career paths – in other words, the world of work beyond the stem cell laboratory. There are, after all, interesting careers awaiting stem cell researchers in patenting, media, specialist publishers and science communication.

Workshops for scientists in executive positions

Once a year, the GSCN holds a multi-day workshop for the smaller target group of young scientists aiming for academ-ic leadership positions. The workshop is not just relevant to experienced post-docs: “Anyone who does a PhD will end up in a leadership position at some point – and they need to be prepared for that,” says Schröder. The workshop-style course is held by a professional coach for ten to twenty participants. The last intensive course focused on a topic of nothing less than existential importance: How do I write a funding application for my own position? Many people are not aware of the diversity of funding options available to stem cell researchers, says Schröder.

Nonetheless, it is clear that stem cell researchers aiming for an academic career in Germany will be confronted with harsh realities. The situation has become especially difficult in the university environment. Public research institutes offer very few permanent positions for scien-tists other than professorships. “The mid-level faculty structures are still very underdeveloped,” says Schröder with regret. “Permanent positions for lab managers for example are urgently needed,” she adds. Most of the po-sitions are externally financed with third-party funds and the institutions themselves are having to cope with ever tighter budgets. This means that most posts are tempo-rary. To make the system more flexible again, experts are calling for more permanent positions that are, however, regularly subjected to quality controls and adapted ac-cordingly.

More tenure track professorships on the horizon

The good news is that the federal government intends to improve the prospects of young academics. The Federal Ministry of Education and Research (BMBF) is launching its tenure track program in 2017. This will see the federation investing one billion euros in a pact with the federal states to set up 1,000 additional tenure track professorships at universities. Geiger and Schröder regard this is as a long overdue step in the right direction. The “new” Excellence Initiative, agreed on last year, is also set to give fresh mo-mentum to the research landscape across Germany from 2019. This time round, the strategy includes a separate funding line for smaller universities and technical colleges called “Innovative Hochschule”.

The 2013 National Report on Junior Scholars, BuWIN 2013, shows that eighteen months after completing their PhD, 44 percent of bioscientists are still working in research (31 per-cent at universities, 13 percent at non-university research institutes), while 29 percent are in the public sector and 27 percent in private enterprise. There is a definite trend towards private enterprise, which is hardly surprising as it offers good payment, permanent positions and promising career development opportunities. Many people are not actually aware of the diversity of jobs open to them. Along-side pharmaceutical companies, there are also interesting career prospects in the biotech industry. The annual corpo-rate survey by web portal biotechnologie.de revealed that in 2015 around half of the 600-odd German biotech com-

paniesoperate in the medical sector, covering a broad spectrum of fields from drug development to di-agnostics. Clinical research organiza-tions (CROs) that conduct clinical trials on behalf of phar-maceutical developers also have attractive positions for qualified stem cell researchers.

Taking a broader view and grasping opportunities

Anke Raloff from academics.de, a career portal that pro-vides extensive information for scientists looking for a job as well as running the online job market of the newspaper Die Zeit, advises graduates to think about career paths out-side academia at an early stage. “Many career starters only look at their academic qualifications and the requirements stipulated by companies in their job descriptions.”

Raloff’s expert advice for young professionals is rather to rely on their own strengths and skills and to broaden their view of the options open to them. She advises jobseekers to “look at the opportunities outside of their narrow qualifi-cation tunnel” and have the courage to apply for positions

even if they are not an exact fit to their professional qualifications.

She says it is also well worth going to job fairs and talking to companies

there directly. And, of course, the young professionals should also come to the GSCN

annual conferences, where the industry exhibi-tion includes precisely those companies most rele-

vant to stem cell researchers.

While preparing her lectures offering extensive tips on job applications, such as the one she gave at the 2016 GSCN Annual Conference in Hannover, Raloff often browses the Internet looking for inspiration from corporate websites with good career pages of their own. “Companies that have a dedicated section for job applicants and that provide a lot of information show how important it is to them to recruit top talent.”

Better work-life balance and more family time

Even though the air definitely gets thinner in the higher ranks of academic research, Insa Schröder remains opti-mistic. “In my experience, if someone is passionate about their work, they will find a way.” Nonetheless, embarking on a career in research requires a certain degree of flexibil-ity and mobility.

This stands in stark contrast to the expectations of the cur-rent generation of students who want more job security and, increasingly, a better work-life balance. Fortunately, things

have changed in this respect at the research institutes, says the Ulm-based biomedical expert Geiger: “The days when your prospects for promotion went hand in hand with the number of hours you spent in the lab are over.” A bit more nous is what’s required to tackle today’s complex tasks suc-cessfully and you can switch that on at home, too.

Another priority issue for the GSCN is to focus more on the careers of women working in stem cell research. The Female Scientist Award, a special prize awarded by the GSCN at its annual conference each year, is an example of the network’s efforts in this area. The proportion of fe-male researchers working in leading positions in science and private enterprise is still very low. Insa Schröder sees the award as sending a very powerful message. “The award-winners are role models that show how successful women can be in top-level research.” Hartmut Geiger also emphasizes how important diversity is for the German re-search landscape and for the GSCN.

Supporting young researchers is not just about helping them choose their career paths and preparing them for their chosen careers. Many doctoral students and post-docs are also first-time parents or already have more than one child. The Career Development working group also wants to address this issue. The GSCN is currently consid-ering setting up a financial support scheme to make it eas-ier for young families to combine childrearing with their research work and help them to maintain the momentum in their careers.

The Collaborative Research Center SFB 873Maintenance and differentiation of stem cells

The Collaborative Research Center SFB 873 “Maintenance and Differentiation of Stem Cells in Development and Disease” at Heidelberg University works towards defining the regula-tory principles underlying the balance between maintenance, expansion and differentiation of stem cells in diverse systems on a mechanistic level. To this end the SFB873 studies a wide spectrum of experimental models ranging from plants to human to elucidate the inherent properties of specific stem cell systems, but also to uncover common and divergent principles behind regulatory regimes and molecular signa-

tures. Our consortium brings together internatio-nally recognized researchers, with unique scientific strengths in cell biology, biophysics, developmental biology, molecular medicine or modeling. With our research we hope to advance our understanding of principles underlying stem cell function and lay the foundation for translational approaches.

PUBLIC OUTREACH

Stem cells – learning opportunities for everyone

Advancing awareness and understanding: GSCN public outreach work

On 11 March 2016, groups of school students flocked to sci-entific institutions in eight German cities, researchers kitted themselves out with nametags and steeled their nerves, and heart surgeons explained to the youngsters how stem cells can be used to treat cardiac disease. It was all part of a major campaign that gave 1,000 high school students chil-dren across Germany the chance to spend the day learning about stem cells. The GSCN’s public outreach work aims to present stem cell research in a simple and intelligible way to all interested parties. It uses a wide variety of different tools and methods to do so, including lectures, one-to-one conversations, videos, interactive games, lab tours, hands-on experiments, exhibitions, flyers and articles, and is constantly adding creative new formats to the list. Students in Hannover were even allowed to watch a lung transplant as part of the public outreach campaign, all in the name of raising awareness and interest in stem cell research and to enable people to form well-founded opinions on the issues concerned. Science communicators are always on the search for new ideas to get particular groups interested in this rapidly advancing field.

In spring 2016, the target group were high school stu-dents taking part in Germany’s first UniStem Day. The German Stem Cell Network and participating institutes

had spent one year organizing and planning this event to make it a success. UniStem Day is the first centrally organ-ized educational day in Germany dedicated purely to stem cell research. The goal of the event was for exhausted and fascinated students to go home in the evening with an un-derstanding of the potential of stem cells, the significance of their versatility, and what cell reprogramming is all about. They would have grasped why research is not the same as treatment, why research often seems to take so long, how to become a researcher and why it is so important that ethics, reflection and social debate accompany developments in stem cell research. These kinds of public outreach activities are designed to in-troduce young people, future researchers and future patients and their relatives to the fas-cination and also the realities of research at a very early stage.

The GSCN has set itself the task of ad-vancing awareness and understanding of stem cells within society. It aims to present the complex web of scientific findings, the associated ethical im-plications and the long developmen-tal path towards translation, clinical trials and treatments in a way that is

understandable to the general public and to decision-mak-ers. This also means that stem cell researchers must be prepared to listen to the fears and concerns of diverse civ-ic groups and individuals and explain the facts in formats such as panel discussions and interviews. “I recently took part in a discussion on stem cell research with theologians and Catholic business people and it proved to be extremely interesting and enriching for both sides,” says GSCN man-aging director Daniel Besser, who appreciates opportuni-ties to discuss the subject with groups traditionally situat-ed at the opposite end of the spectrum. “Stem cell research is a very complicated field so we cannot expect everybody to immediately understand the material and the impli-cations involved.” For the GSCN, it is therefore important that its public outreach activities include many different formats that match the level of knowledge and communi-cation styles of all the various target groups in question, from students to patients and the elderly. “We tend to find that elderly people are particularly interested in our public events and specially designed series of exhibitions on stem cells and disease,” explains Besser. Short videos on stem cell researchers and their work are shown at the GSCN events to give participants an easily understandable introduction to the debate. It is absolutely essential to stick to the facts. The GSCN takes care not to exaggerate the achievements of the research or play down or ignore the associated risks. “It is very important to us not to stir any unfounded fears or raise unfounded hopes,” says Besser.

The need to improve public understanding and for effective science communication became apparent when stem cell research first came into the public eye in a big way. The me-dia attention generated by a stem cell researcher’s applica-tion to use human embryonic stem cells for research pur-poses in 2002 and the discovery of iPS cells in 2006 sent the demand for information and debate through the roof.

“A lot of journalists and patients called us up at the institute asking about stem cells, iPS cells and the opportunities and risks involved,” says Tobias Cantz. He was working at the Max Planck Institute for Molecular Biomedicine in Münster at the time, in the laboratory of Hans Schöler, the research-er at the center of the attention in 2006. “As a physician, I am experienced in telling patients carefully but clearly about their medical situation and their treatment options. I transferred this attitude to the way I approached the gener-al public.” In Münster, one of the hotspots of the debate on stem cell research, biomedical scientists and ethic experts set up a website on stem cell research in partnership with the Protestant Church. It is called Zellux and is targeted at schoolteachers and school students. “We wanted to create a website that provides validated high-quality informa-tion on the subject. The internet was awash with so much unverified information at the time, some of which was completely unfounded and absurd. So we wrote all of the information and teaching material for the site ourselves.”

Since then, Tobias Cantz has been not just a re-

searcher but also passionately

in public outreach work. Even after ten years of experience working with school classes and teachers, the young profes-sor still takes a keen interest in observing and contributing to the development of students’ attitudes and arguments. “I consider this is a really important part of my work. It gives me the chance to hear the opinions of the younger genera-tions and I particularly enjoy talking with them about eth-ical principles.” His work with young people keeps Cantz curious. And he has noticed that the vehemence of the pub-lic debate on stem cell research has declined and been re-placed by a more practical take on ethics. Asked about his wishes for the future, he says that he would like to provide students with even better information so that they can bet-ter understand and discuss the dynamics, the potential and also the ethical issues involved in recent developments in biomedicine. To achieve this and also to counter knowledge gaps in the future, Cantz is currently serving as expert advi-sor for the teaching material being developed for schools in Germany by the German Stem Cell Network and the Ernst Schering Foundation. The material will be available from May 2017 on the website www.stammzellen-verstehen.de

“One of the first target groups of our public outreach work were politicians,” says Ira Herrmann, coordinator of the GSCN working group on public outreach together with To-bias Cantz, reflecting on her time as managing director of the competence network for stem cell research of North-Rhine Westphalia. Following Prof. Oliver Brüstle’s applica-tion to use embryonic stem cells for research purposes in 2002, she was inundated with inquiries on the topic. She focused her public relations work on politicians and the press but also served the information needs of interested members of the general public. The research findings re-ported on by the media soon sparked the interest of another group, namely patients. “They called us desperately want-ing treatment that we were obviously not able to provide. It’s sometimes difficult to offer objective advice in such cas-es,” says Ira Herrmann. She came up with a new approach to help remedy this situation, initiating a lecture as part of further training measures for family physicians to inform them about the opportunities and risks of stem cell thera-pies. “We were thus able to reach out to the disseminators who are the first point of contact in healthcare matters and are often in direct contact with people with chronic illness-es over many years,” says Hermann. In the first few years Hermann provided patients directly with information in English from Canada and the US before she created a Ger-man website on the subject together with the competence network team. In 2016, she summarized the facts and ques-tions on non-validated therapies and important aspects for patients in a flyer on behalf of the GSCN. This gives patients answers to their most pressing concerns and puts them in a position to ask the right questions themselves, for example of providers of stem cell therapies. Ph

PUBLIC OUTREACH

The German Stem Cell Network has engaged in a variety of new activities since 2013, including public panel discus-sions and films on German stem cell researchers and their work, all of which are designed to encourage the interested public to think about stem cells. “We have been able in the meantime to develop a range of tried and tested methods to reach as many groups as possible,” says Daniel Besser. The biggest campaign so far was UniStem Day, and the most re-cent effort is to create up-to-date teaching material for four teaching modules, presented to students in the form of a conference. The network is now setting its sights on creat-ing a film portal with GSCN-produced researcher portraits, like the ones in the United Kingdom that have made it onto the bestseller click list of the European outreach network EuroStemCell.

GSCN ANNUAL REPORT

Activities in 2016In 2016 the GSCN tried out new ways of engaging with the public and consolidating its role as a net-work. The public outreach working group of the GSCN initiated and organized a new national stem cell day for senior high-school students. Regarding public affairs, the GSCN presented political deci-sion-makers with an analysis of public funding for stem cell research triggering much-needed discus-sion on the issue. In its capacity as a network, the GSCN initiated new formats and stepped up its par-ticipation in international conferences and interna-tional networking workshops.

The network

The GSCN Annual Conference is the largest and most important meeting of stem cell researchers in Germa-ny. Around 400 scientists gathered at the 4th GSCN Annual Conference held at the Hannover Medical School. The conference provided ample opportunity for scientific exchange and to spark new plans and cooperations. A new and original aspect was the Networking Evening in the zoo: glorious summer temperatures and great design of the zoo provided the perfect setting to forge contacts, discover profes-sional and personal commonalities, and make new friends. Personal networks play an important role in the initiation and success of current and future pro-jects. In the follow-up to the conference, participants extensively addressed the topic of trouble shooting at the Non-PI Meeting in Hannover (15 Sept. 2016), a GSCN format that has become an established and much appreciated event.

On an international level, the GSCN brought people together at the ISSCR Annual Meeting in San Fran-cisco (22 – 24 June 2016) with its second Wunder-Bar Evening. The event, held in a brewery, was at-tended by around 95 guests and was deemed a great success. The traditional GSCN Meet-Up Hub took place in the exhibition area of the ISSCR Meeting and attracted many German and international GSCN

members and their colleagues who valued the oppor-tunity for intensive exchange in the middle of the con-ference. Among them were the six junior scientists who had won the chance to cross the big pond to the ISSCR courtesy of the GSCN Travel Awards granted by the GSCN working groups. The travel award recip-ients were: Avni Baser (Heidelberg), Cristina Golfieri (Dresden), Stefan Hauser (Tübingen), Chao Sheng (Bonn), Manuela Völkner (Dresden), and Stefan Weiss (Munich). They were all extremely impressed by the inspiring atmosphere of the big international confer-ence, the diversity of the sessions and the academic qualify of the lectures as well as the presence of re-nowned international figures in stem cell research.

Networking means forging contacts that can help advance one’s work and professional career. The GSCN Awards are awarded by the GSCN as a means of promoting promising careers and motivating oth-er young researchers. In 2016 the GSCN awarded three prizes endowed with €1,500 and the chance to give a lecture at the central Presidential Symposium at the GSCN Annual Conference:

• The GSCN 2016 Young Investigator Award went to Dr. Leo Kurian from the Center for Molecular Medicine Cologne (CMMC) of the University of Cologne.

• The GSCN 2016 Female Scientist Award went to Prof. Claudia Waskow from the TU Dresden.

• The GSCN 2016 Publication of the Year Award went to Dr. Guangqi Song, Dr. Martin Pacher, Prof. Michael Ott and Dr. Amar Deep Sharma from the REBIRTH Center and TwinCore at the Hannover Medical School for the publication “Direct Reprogramming of Hepatic Myofibro-blasts into Hepatocytes In Vivo Attenuates Liver Fibrosis“ in the journal Cell Stem Cell (Song, G. et al., 2016, Cell Stem Cell, 18, 797 – 808, doi: 10.1016/j.stem.2016 .01.010.).

GSCN ANNUAL REPORT

The GSCN also takes part in, supports and organ-izes workshops, sessions and seminars with other organizations to foster its contacts on a scientific, administrative and collegial level: The GSCN was Silver Supporter of the ISSCR Meeting in Dresden (1 – 3 Feb. 2016) providing scientific and finan-cial support as well as organizing the session on “3D Cultures & Organoids”. At the IGDL Meeting in Hamburg (25 – 27 Feb. 2016) the GSCN was pa-tron of a satellite symposium on deepening “special knowledge”. At the PluriCore-Meeting in Berlin (19 – 20 May 2016), supported by the GSCN, core facility staff from across Germany met to share new protocols and ideas. “We are extremely grateful to the GSCN for its generous financial, logistical and scientific support,” said Sebastian Diecke at the opening of the meeting. At the annual conference of the DGTI in Nuremburg (7 – 10 Sept. 2016), the GSCN organized a satellite symposium with Thom-as Brabletz, Robert Zweigerdt, Susanne Kleber and Gerald Schumann. In 2016, the GSCN supported the following events:

• StemCellMathLab Workshop (16 – 18 June) in Hamburg

• 3rd Conference on Cell Therapy Manufacturing and Testing (2 – 3 Nov.) in London, UK

• Workshop on Computational Tools for Sin-gle-Cell Transcriptomics (14 ov.) in the Helm-holtz Zentrum München

• 2nd Challenges in Computational Biology: Gene Expression Analysis Conference (1 – 2 Dec.) with a satellite student Symposium on Computational Genomics (30 Nov.) in Mainz

A GSCN PEI Workshop (10 Nov. 2016) in Langen was dedicated to regulatory matters regarding the development and clinical application of pluripo-tent stem cells. The strategic working group Career Development organized a two-day further training course “How to write a successful grant applica-tion to support yourself” for 12 junior investiga-tors in Ulm (24 – 25 Nov. 2016). The workshop was booked out very quickly and was rated as extremely helpful in the feedback. “We hope that all the par-ticipants will be able to put what they learned to use in the near future and be successful in their applications. Watch out reviewers, from now on all applications for stem cell research will be perfectly worded!” said event organizer Hartmut Geiger on the course and outcome of the workshop.

The GSCN also took another important step with its evaluation by the implementing agency VDI-TZ. At the milestone meeting on 3 June 2016, VDI-TZ attested that the GSCN conducts outstanding work and has delivered on all parts of the project. This in-cludes building up the network, attracting members and growing membership, organizing a range of events (conference, satellite symposia, workshops), setting up working groups, providing information and performing public outreach work.

In 2016, the GSCN again granted Travel Awards to enable talented junior scientists to take part in various conferences and summer/winter schools. Thanks to these awards, Birte Baudis (Cologne), Christian Böhme (Leipzig), Larisa Condurat (Frei-burg), Nora Freyer (Berlin), Devy Garna (London) and Florian Murke (Essen) were able to attend the GSCN Annual Conference in Hannover. All Travel Awards were funded by GSCN company member Eppendorf AG. Also in 2016, the GSCN granted Travel Awards to Jerome Korzelius, Jena, to attend the Gordon Research Conference: Tissue Niches & Resident Stem Cells in Adult Epithelia in Hong Kong; Goveas Neha, Dresden, for the Hydra XII Summer School; Marisa Karow, Munich, to go to the Annual Meeting of the Society of Neuroscience in San Diego; Nancy Mah, Berlin, for the 2nd Chal-lenges in Computational Biology Gene Expression Analysis Conference in Mainz and Miriam Hetzel, Hannover, for the ISSCR/ESGCT International Sym-posium in Florence.

GSCN ANNUAL REPORT

Communication

A network is based on communication and the ex-change of information – both on a scientific and a personal level in the working groups, at the confer-ence, and in the workshops and committees. There were two particularly striking highlights in the GSCN’s communication activities this year. First, the GSCN published its white paper “Public funding of stem cell research – Germany in internation-al comparison” presenting it to a group of German Bundestag politicians and public officials in Berlin on 28 Sept. 2016. The paper’s analysis between the US, the UK, Sweden, Japan and Germany showed that while public funding for stem cell research has been declining in Germany, it has rising stead-ily in the other countries investigated where the cross-cutting technology is regarded as a driver of innovation. The objective of the GSCN white paper is to persuade politicians to step up their political and financial support for stem cell research to ena-ble Germany to maintain its leading global position in this field.

A new highlight of the GSCN in 2016 was the first UniStem Day. The GSCN organized an educa-tional day for school students across the whole of Germany. On 11 March 2016 approximately 1000 school students in eight cities flocked to a total of 17 research institutes to spend the day learning all about stem cell research through games, films, lab tours, lectures, speeches, expert consultations and company tours. The feedback from the institutes, researchers, teachers and students was extremely positive. Not only German school students spent the day learning about stem cell biology – a total of 27,000 school students across Europe dedicated the day to learning about stem cells. The UniStem Day was also the topic of a project presentation given by

Stefanie Mahler at the forum on scientific commu-nication, Forum Wissenschaftskommunikation, in Bielefeld (5 – 7 Dec. 2016). The UniStem Day also showed how constructive and successful the work of the GSCN Communication on Stem Cell Re-search group has been in getting the participating institutes involved.

School students were the target audience of the GSCN events at the debate on stem cells and eth-ics at Haus Kreisau youth education center (28 Jan. 2016) and at the MINT400 Forum in Berlin in Adlershof (4 – 5 Feb. 2016). For students wanting to learn more about new professional fields, Daniel Besser offered tours around the campus as part of international seminars (29 Feb. and 2 March 2016) and discussed stem cell research with young US scientists in the program of the Council on Interna-tional Educational Exchange (CIEE).

Internationally, the GSCN collaborates closely with EuroStemCell. The two networks jointly organized the workshop “Train the Trainer 2” (31 Oct. – 1 Nov. 2016) in Berlin. The GSCN was the host for 25 international science communicators who spent two days exploring possible ways of communicat-ing stem cell research. There was much discussion, sharing of experiences, projects, methods and ma-terials and the participants learned a lot from one another.

For the interested general public, the GSCN held a panel event in the follow-up to its Annual Confer-ence in Hannover (14 Sept. 2016). Facilitator Ste-fanie Seltmann (DKFZ) and panel members Axel Haverich, Ulrich Martin, Michael Manns, Tobias Cantz (all from MHH) and Nils Hoppe (Leibniz Uni-versität Hannover) debated the possibilities of stem cell therapies in treating heart and liver disease.

The latest GSCN films about Michael Manns and Tobias Cantz, Ulrich Martin and Nils Hoppe were also shown. These have now been translated into English and are also available on the GSCN web-site at: www.gscn.org/en/RESOURCES/GSCNMovies.aspx.

Cultivating contacts within a network always also involves passing on information. The GSCN makes use of various communication channels. At the con-ference the annually updated mobile app “GSCN 2016” enabled participants to shape their visit to the conference to suit their personal interests. The GSCN also provides information and news in Eng-lish and German on its website www.gscn.org. The website’s news column that spotlights internation-al articles on the latest developments in the field is particularly popular. The GSCN films, job market and conference announcements also attract great interest. By email, the Central Office sends out the GSCN Newsletter, which focuses on different topics in each issue. In 2016, the GSCN published a new image brochure, the annual magazine 2015/16 (1,100 copies) and a patient flyer with information on the latest developments in stem cell therapies and questions that patients should ask before they opt for a particular treatment. The internal commu-nication platform Humhub serves as a forum for all members and is used in particular by the Central

Office to provide advance information on work-shops, conferences and to call for applications for travel grants.

The GSCN is also active on social media including Facebook, LinkedIn and Twitter and has a growing number of followers. The GSCN Central Office reg-ularly receives inquiries from teachers, students, patients and journalists, which are answered with the help of scientists. The GSCN conference, in par-ticular, prompts nationwide coverage in print and online media.

FinancesThe GSCN is a non-profit organization funded by membership subscriptions and grants from the BMBF. Under Section 4 of its statute, the level of subscriptions is set by rules adopted at the General Assembly. Subscriptions are detailed on the GSCN’s membership form.

The business year is the calendar year. Subscrip-tions are due at the start of the business year. The Executive Board is responsible for producing the an-nual accounts and submitting them to the General Assembly. Details of the association’s finances are provided at the General Assemblies.
