DanStem Executive Director, Professor of Human Stem Cell Biology
Link to the Semb Laboratory Homepage
With a career spanning over 15 years Henrik Semb’s multi-disciplinary approach to research has contributed to the advancement of several scientific fields. The lab has used a combination of in vivo and in vitro tools to decipher a range of cellular mechanisms, from tumor cell invasion and metastasis, to basic mechanisms in morphogenesis and differentiation during organogenesis. Henrik’s main goal is to understand the basic fundamental cellular and molecular mechanisms of organogenesis. Examples of recent ground-breaking discoveries in this area include Kesavan et al Cell, 2009, Funa et al Cell Stem Cell, 2015, and Löf-Öhlin et al Nat Cell Biol, 2017. Most recently, the lab has identified how mechanosignaling, via integrins, acts as a gate-keeper for pancreatic progenitor fate decisions (Nature, in press). Henrik’s long-term interest and experience in translating basic research results (e.g. Ameri et al Cell Reports, 2017) into clinical applications has also led to an ambitious program on human pluripotent stem cell-based cell therapy in Type 1 Diabetes. As director of the Danish Stem Cell Centre (Danstem) Henrik encourages an integrated research environment both between and within research groups
Grants and Awards
Henrik Semb’s scientific achievements in pancreas development and the beta cell biology field have been recognized by many international and national grant-awarding bodies throughout his research career, including; the EU, EMBO, Swedish Foundation for Strategic Research, the Swedish Government, the US National Institute of Health (NIH) and the Juvenile Diabetes Research Foundation. Currently Henrik is the Executive Director of Danstem, which is funded by the Novo Nordisk Foundation for a 10-year period. From 2011-2016 Henrik headed the a Section for Strategic Translational Stem Cell Research and Therapy, which was funded by a 6-year grant from the Danish Council for Strategic Research. He coordinated the collaborative EU FP7 project HumEn between 2014 and 2017 with the aim of achieving robust generation of functional beta cells from hPSCs. Lundbeckfonden awarded a 3-year project grant to the Semb lab to investigate how an endocrine cell’s niche directs fate choice to specific hormone producing differentiated cells and the Danish Council for Independent Research, Medical Sciences (FSS) awarded project grants in 2013 and 2016 for work related to investigating the role of polarity during pancreas progenitor cell differentiation.
In addition to leading his research group and the centre, Henrik is also committed to engaging in the wider stem cell and pancreas research field. Henrik has served as a member of the International Stem Cell Initiative steering committee and serves as an Editorial Board member of Stem Cells and Stem Cell Reports. He also engage in various outreach and educational activities to explain the need for basic research, how it related to translational applications and the risks with unrealistic expectations for rapid solutions to new stem cell-based therapies.

Professor.Semb acted as a scientific advisor within Cellartis AB, a company which he co-founded. Cellartis was a Gothenburg based SME with 62 employees and an annual revenue of €6million that commercialized various human ES cell applications. Cellartis was purchased by Cellectis (France) in 2011, Cellectis was subsequently bought in 2014 by Takara bio inc.
As part of a 3-party collaboration between Lund University (Semb), Novo Nordisk a/s and Cellartis/Cellectis Henrik worked to develop a hESC-based cell therapy for diabetes (2008-2013).
Professor Semb is also a cofounder (along side Dr Jacqueline Ameri) of a spin-out company arising from the Novo Nordisk Foundation Center for Stem Cell Biology (DanStem), at the University of Copenhagen. The company is aiming to develop a next generation stem cell derived allogeneic cell therapy (PanINSULA™) for type 1 diabetes.
