Irving Weissman

Irving Weissman, MD, is director of the Stanford Institute for Stem Cell Biology and Regenerative Medicine, Professor of Clinical Investigation in Cancer Research, Professor of Developmental Biology, and, by courtesy, of Biology. As the first scientist to identify and isolate mammalian blood-forming stem cells in mice, Dr. Weissman is an expert in stem cell biology and hematopoiesis, cancer stem cells, and macrophage immune checkpoints. His group has successfully defined the stages of development that occur between stems cells and mature progeny. Dr. Weissman’s lab was the first to identify, prospectively isolate, and transplant human and murine HSCs. He earned an MD from Stanford University and a BS from Montana State College.
