Society: Stem cell donation for US patient

A female medical worker in Shanghai has become the first hematopoietic stem cell donator this year to help an overseas patient. The recipient is a resident in the United States with leukemia. Xiong Qian, director of Shanghai Gonghui Hospital’s endocrinology department, donated the hematopoietic stem cells — found in the bone marrow of adults and used to treat blood diseases such as leukemia — at Shanghai General Hospital in late January. About 414 milliliters of her hematopoietic stem cells were collected and transported to the US.
