Johannes (Hans) Carolus Clevers (born 27 March 1957) is a Dutch molecular geneticist, cell biologist and stem cell researcher. He became the Head of Pharma, Research and Early Development, and a member of the Corporate Executive Committee, of the Swiss healthcare company Roche in 2022. Previously, he headed a research group at the Hubrecht Institute for Developmental Biology and Stem Cell Research and at the Princess Máxima Center; he remained as an advisor and guest scientist or visiting researcher to both groups. He is also a Professor in Molecular Genetics at the University of Utrecht.
Early life and education
Hans Clevers was born in Eindhoven, the Netherlands in 1957. He began studying biology at the University of Utrecht in 1975, but also started taking medicine in 1978, in part due to his interest and in part because his friends and brothers were in the medical profession. He spent 1 year in Nairobi, Kenya, and half a year at the National Institutes of Health in Bethesda, United States, for biology rotations. He received a Doctoraal (equivalent to an MSc) in Biology in 1982 and an Artsexamen (equivalent to an MD) in 1984. Mostly because of his research background, Clevers was selected for a training position in paediatrics, and then went to pursue a PhD in 1985, under the supervision of Rudy Ballieux. He obtained his PhD 1 year later.
Career
After his PhD, Clevers went to the Dana–Farber Cancer Institute as a postdoctoral researcher at Cox Terhorst's group. In 1989, he returned to the Netherlands, joining his alma mater, the University of Utrecht, as an assistant professor at the Department of Clinical Immunology.
In 1991, Clevers became a professor and the chair of the Department of Immunology at the University of Utrecht. He moved to the University Medical Center Utrecht in 2002 as a professor in molecular genetics, and started his lab at the Hubrecht Institute for Developmental Biology and Stem Cell Research (Hubrecht Institute). At the same time, he took up the position of Director of the Hubrecht Institute.
In March 2012, Clevers was elected the president of the Royal Netherlands Academy of Arts and Sciences, succeeding Robbert Dijkgraaf. His term concluded in 2015, and he started another lab at the Princess Máxima Center, focusing on childhood cancer, and became the Director Research and Chief Scientific Officer there until 2019.
Clevers left University Medical Center Utrecht and was appointed Professor in Molecular Genetics at the University of Utrecht in 2020.
In 2022, Clevers joined the Swiss healthcare company Roche as its Head of Pharma, Research and Early Development and a member of its Corporate Executive Committee. He remains an advisor and guest scientist or visiting researcher to his research groups at the Princess Máxima Center and Hubrecht Institute.
Since 2017, Clevers is an investigator at the Oncode Institute in Utrecht.
Clevers has served at a number of scientific organizations, including on the board of directors of the American Association for Cancer Research (2013-2016), and the Scientific Advisory Board of the Swiss Institute for Experimental Cancer Research at the École Polytechnique Fédérale de Lausanne (2005-2015), the Research Institute of Molecular Pathology in Vienna (2015-2021) and the Francis Crick Institute in London. He is currently on the advisory board of various scientific journals, including The EMBO Journal, Disease Models & Mechanisms, Cell, Cell Stem Cell and EMBO Molecular Medicine. From 2014 to 2022, he was also on the editorial committee of the Annual Review of Cancer Biology.
Outside the academia, Clevers has been a scientific advisor to numerous biotechnology companies. He also co-founded California-based Surrozen in 2016 and Shanghai-based D1 Medical Technology in 2019.
Research
Clevers's early career focused on the Wnt signaling pathway. His group identified the TCF1 protein, a member of the TCF gene family and a crucial downstream component of the Wnt signaling pathway, making it central in immune responses, embryonic development and tissue repair. His interest in the gastrointestinal tract began with the discovery that another TCF family member, the TCF4 protein, is required in forming intestinal crypts. Collaborating with Bert Vogelstein, he found that in colon cancer where the APC gene is doubly mutated, TCF family members activate catenin beta-1, which then enhances the expression of many genes that cause cancer transformation, connecting the Wnt signaling pathway with colon cancer.
In 2007, Clevers's group identified a marker for stem cells of the small and large intestines, LGR5, itself also a target of the Wnt signaling pathway. This led to his finding that LGR5 is a stem cell marker in other organs as well, including the stomach and hair follicles.
Building on this discovery, in 2009, his group published a landmark paper, describing for the first time how organoids, which are 3-dimensional in vitro structures that behave anatomically and molecularly like the organ from which they are derived, were generated from adult stem cells, creating organoids of the small intestine. Clevers's group has applied this technology to culturing organoids from other organs, such as the stomach and liver, as well as from various cancer types, including cancer of the breast and the ovaries. This platform has since been applied in personalized medicine, by generating organoids from specific patients to screen for drugs. This is not limited to cancer but is applicable to other diseases as well (for example, cystic fibrosis). His current major research interest is in using organoids derived from adult stem cells to study the molecular mechanism of tissue and cancer development.
During the COVID-19 pandemic, Clevers's group modelled the infection of SARS-CoV-2 using lung organoids.
