The most important aspects of research relating to the treatment of hematological cancers are characterization, localization, and identification of these hematopoietic stem cells. The main source of these stem cells is the bone marrow; about 1 in every 100,000 cells in the bone marrow is a hematopoietic stem cell. Second, peripheral circulating blood is another good source of hematopoietic stem cells and increasingly is becoming a preferred option in the clinical setting. Finally, human umbilical cord blood and cells from the placenta are also sources of hematopoietic stem cells. Clinical researchers are focused on how to expand the number of cells available in a stem cell culture after isolation from these sources.
