This article is based on interviews with Drs. Martin Pera, Peter Andrews, Tenneille Ludwig, Benjamin Rubinoff, and Outi Hovatta, leading stem cell researchers and pioneers within pluripotent stem cell research. Those who have been along for the entire ride. Enjoy!
Benjamin Reubinoff, M.D., Ph.D.
Professor, Hadassah University Medical Center, Jerusalem Israel
Professor Reubinoff is one of the pioneers of human embryonic stem cell (hESC) research. In collaboration with scientists from Monash University in Melbourne and the National University of Singapore, he was the second in the world to derive human embryonic stem cell (hESC) lines and was the first to show somatic differentiation of the hESCs in culture. Prof. Reubinoff is the founder and director of the Sidney and Judy Swartz Human Embryonic Stem Cell Research Center and a full professor and chairman of the Department of Obstetrics and Gynecology at the Hadassah University Medical Center in Jerusalem. The focus of Prof. Reubinoff’s research is the exploitation of human embryonic stem cells (hESCs) in regenerative medicine for the treatment of neural and retinal degenerative disorders. He is the founder of Cell Cure Neurosciences Ltd. and has been the Chief Scientific Officer since 2006. He is also a member of the Scientific Advisory Board at Kadimastem Ltd. His work on human pluripotent stem cells helped lead to the development of programs that are now in clinical trials in Israel.
Peter Andrews, B.Sc, MBA, DPhil,
Arthur Jackson Professor of Biomedical Sciences, University of Sheffield, UK
Professor Peter Andrews has devoted his research career to studying the biology of human embryonic stem (ES) cells and their malignant counterparts, embryonal carcinoma (EC) cells. Prof. Andrews was the first scientist in the UK to work with human ES cells, following the first derivation in 1998. Prof. Andrews’ laboratory studies the causes and consequences of the non-random genetic abnormalities observed in human ES cells after prolonged culture, as well as the progression of stem cell-based cancers. Further work is focused on using induced pluripotent stem (iPS) cell techniques to establish models to study pediatric cancers. Prof. Andrews was a co-founder and director of Axordia Ltd., one of the UK’s leading hESC companies (now a subsidiary of Pfizer) and has been involved in the derivation of several clinical-grade hESC lines (the Sheffield lines), deposited in the UK Stem Cell Bank. Prof. Andrews coordinated the International Stem Cell Initiative and was the director of the Pluripotent Stem Cell Platform, a hub under the UKRMP. He is also on the editorial board of several stem cell journals.

Martin F. Pera, Ph.D.
Professor at the Jackson Laboratory, Bar Harbour, Main, USA
Professor Martin F. Pera is a pioneer and leading stem cell researcher with interests in neuroscience and regenerative medicine. His laboratory at Monash University was the second in the world to isolate embryonic stem cells from the human blastocyst, and the first to describe their differentiation into somatic cells in vitro. His work on neural differentiation of human pluripotent stem cells helped lead to the development of a new treatment for macular degeneration, which is now in clinical trials in Israel. Prof. Pera joined the Jackson Laboratory in 2017 where his research focuses on the biology and regulation of pluripotency and the genetic basis of individual differences in the response of the central nervous system to injury.
