Korean researchers have for the first time extracted hematopoietic stem cells that could help treat leukemia from fatty tissue. According to the Ministry of Education, Science and Technology, Korea, the discovery was made by a research team led by Koh Gou-young, a biologist at the Korea Advanced Institute of Science and Technology. Leukemia affects hematopoietic stem cells in the bone marrow. Until now, it has been treated by bone marrow transplant from donors. The Korean success will open up possibility of extracting hematopoietic stem cells from a patient's own fatty tissue.
