Bone marrow is the spongy tissue inside some of the bones in the body, including the hip and thigh bones. Bone marrow contains immature cells, called stem cells.
Many people with blood cancers, such as leukemia and lymphoma, sickle cell anemia, and other life-threatening diseases, rely on bone marrow or cord blood transplants to survive.
Healthy bone marrow and blood cells are needed to live. When the disease affects bone marrow so that it can no longer function effectively, a marrow or cord blood transplant could be the best treatment option; for some patients, it is the only potential cure.
Bone marrow produces 200 billion new red blood cells every day, along with white blood cells and platelets.
