Dr. Weissman’s research on hematopoiesis, hematologic malignancies and solid tumors has led to several discoveries and the development of new therapies. These include: isolation and transplantation of pure hematopoietic stem-cells (HSCs), development of non-toxic Antibody-based conditioning for HSC transplantation, and the discovery on leukemic stem-cells of CD47 as a ‘don’t eat me’ signal used by leukemias and all human cancers tested to evade innate immunity. He showed that anti-CD47 blockade unleashes phagocytosis of cancer cells by macrophages, and developed cancer immunotherapy, achieving remarkable results in phase-I clinical trials.
