$CIHN Bone marrow transplants have been used for

$CIHN Bone marrow transplants have been used for the past 40 years to regenerate the blood and immune systems of patients with leukemia, lymphoma, severe aplastic anemia or inherited metabolic diseases. Unfortunately, the major limitation with allogenic bone marrow transplants is the availability of matched donors. Successful treatment for leukemia depends on getting rid of all the abnormal leukocytes in the patient, allowing healthy ones to grow in their place. If the bone marrow transplant is successful, the stem cells will migrate into the patient's bone marrow and begin producing new, healthy leukocytes to replace the abnormal cells.
