Ann S. Tsukamoto Weissman (born July 6, 1952) is an Asian American stem cell researcher and inventor. In 1991, she co-patented a process that allowed the human stem cell to be isolated and demonstrated their potential in treating patients with metastatic breast cancer. Tsukamoto has received a total of 13 patents in her career, the majority of them having to do with human hematopoietic stem cells.
Tsukamoto’s research and contributions in the medical field have led to groundbreaking advancements in stem cell research, especially in understanding the blood systems of cancer patients. Her work has shown potential treatments for cancers and neurological disorders, for which there were previously thought to be none.
