Austin Smith (biologist)
Austin Gerard Smith (* 1960 in Merseyside ) is a British biochemist and stem cell researcher .
Smith studied at Oxford and received his PhD from Edinburgh University in 1986 with Martin Hooper. His work on stem cell research began in his dissertation. He was a post-doctoral student at Oxford University before becoming a group leader at the Center for Genome Research in Edinburgh in 1996. This became the Institute for Stem Cell Research, which he led as director. In 2006 he went to Cambridge University . He is Director of the Wellcome Trust / MRC Stem Cell Institute at Cambridge University and Medical Research Council (MRC) Professor.
He is considered a pioneer of stem cell research and researched the mechanism of pluripotency in embryonic stem cells. According to Smith, there is a pluripotent basic state of the cell, in which the cell depends relatively little on the neighboring cells for its growth and survival, but which reacts very sensitively to external disturbances that lead to differentiation processes (caused by cascades of Erk kinases).
In 1986 he succeeded in multiplying undifferentiated pluripotent stem cells in vitro through the presence of a differentiation-inhibiting factor which he initially called DIA (differentiation inhibiting activity) and identified in 1988 with leukemia- inhibiting factor (LIF). Later he was able to determine the effect of LIF (release of various transcription factors) more precisely and develop more specific inhibitors.
In 2010, he saw the main areas of application for pluripotent stem cells in the next decade in disease modeling, toxicological screening and drug development, and in stem cell therapy the best prospects for eye diseases (age-related macular degeneration, retinitis pigmentosum) after it was discovered in 2008 that human embryonic stem cells differentiate relatively efficiently into retinal cells.
In 2010 he received the Louis Jeantet Prize .
He is a Fellow of the Royal Society of Edinburgh (2003) and the Royal Society (2006) and a member of the European Molecular Biology Organization . In 2010 he was accepted as a full member of the Academia Europaea . In 2010 he received the Louis Jeantet Prize , the Pfizer Prize in 2000 and the ISSCR McEwen Award for innovation in 2016.
In 2013, together with other scientists, he criticized the review process in stem cell research in an open letter and suggested making it more transparent.
