Bone Marrow is the soft tissue found inside the bones of the body. Certain cells in the bone marrow (called myeloid tissue or red marrow) of the large bones are responsible for the production of red blood cells, white blood cells and platelets.
Bone marrow can be transplanted from a compatible donor to a person whose bone marrow has been damaged or destroyed. Removal of bone marrow for transplant is a safe process that usually results in minimal discomfort to the donor.
When the bone marrow is diseased, it often has to be destroyed by radiation before new marrow is transplanted.
