Marrow is a tissue found in the large bones of the body.
It produces vital blood components such as white cells which fight infection, red cells which carry oxygen, and platelets which prevent bruising and bleeding. Any disease that attacks your marrow may eliminate your body's ability to protect itself. Most fatal blood diseases have traditionally been fought with radiation or chemotherapy. In countering disease, both forms of treatment may seriously damage the human body. By providing patients in need compatible marrow, you can give them a second chance at a healthy life.
