Hematopoietic stem cells are the precursors of all blood cells. They develop into red blood cells, which carry oxygen, white blood cells, which fight disease and infection, and platelets, which aid in blood clotting.
Hematopoietic stem cell transplantation is the treatment of choice for a large number of diseases of the immune and blood forming systems, including acute and chronic leukemia, lymphomas, immunologic and hematologic disorders, like severe combined immunodeficiency syndrome, and bone marrow failure syndromes, such as severe aplastic anemia.
Stem cell transplantation has also been used to successfully treat a variety of childhood solid tumors, including neuroblastoma, Wilm's tumors, and certain testicular and ovarian malignancies.
