Dr. Weissman has made numerous medical discoveries, but his most important achievement may be developing the general method used to identify and isolate stem and progenitor cells. His first isolation was hematopoietic (blood-forming) stem cells (HSCs) in mice, followed by the isolation of human HSCs. Dr. Weissman’s current research concentration is on the purification, biology, transplantation, and evolution of stem cells. Purified human HSCs have been used successfully to provide autologous stem cell transplants to cancer patients receiving otherwise lethal doses of chemotherapy and radiation therapy.
