Stem cells can divide to become other types of cells. The stem cells found in umbilical cord blood and bone marrow can divide and become red blood cells, white blood cells and platelets. They have been used as part of the treatment therapy in nearly 40 different cancers, immune deficiencies and genetic disorders. More opportunities are being discovered every year but, since each case is different, there is no guarantee that a cord blood transplant will be an appropriate treatment therapy or that it will provide a cure.
Stem cells are used therapeutically for their ability to help restore function to the blood-making and immune systems. This is especially valuable when the systems have been damaged by radiation or chemotherapy.
