Dr. Ihor R. Lemischka is currently both the Lillian and Henry M. Stratton Professor of Gene and Cell Medicine and Director of the Black Family Stem Cell Institute at Mount Sinai Medical Center in New York City.
The focus of Dr. Lemischka’s research is to understand the molecular and cellular nature of the undifferentiated stem cell "states", and how such states are altered during a change in cell fate. The underlying rationale for his studies is that the complement of gene-products and their inter-relationships that exist in stem cells accounts for their remarkable abilities to balance self-renewal and differentiation decision processes. He studies both adult and embryonic stem (ES) cells, primarily from the mouse, but also from the human. His work with "Hematopoietic stem cell" hematopoietic stem cells (HSC) was the first to identify their novel "Receptor tyrosine kinases" receptor tyrosine kinases and showed that HSC can rebuild all blood cell types in a mouse whose blood cells had been destroyed.
Lemischka graduated from Johns Hopkins University and earned his Ph.D in biology from MIT. He did his post-doctoral training at MIT's Whitehead Institute. Lemischka is a board member of the International Society for Stem Cell Research, the Journal of Visualized Experiments (JoVE) and the New York Stem Cell Foundation. His awards include a Damon Runyon-Walter Winchell Postdoctoral, a Leukemia Social Special Fellowship, an American Cyanamid Preceptorship Award and the DuPont Young Faculty Grant. He is a journal reviewer for Cell, Science, Nature, Nature Genetics, Nature Immunology, Nature Biotechnology, Proceedings of the National Academy of Sciences, Public Library of Science, Development, Genes & Development, Journal of Clinical Investigation and Blood.
