A possible cure for some people with sickle cell anaemia is a bone marrow or stem cell transplant. Your bone marrow contains stem cells, which are the most basic kind of blood cell. These stem cells mature into red blood cells, as well as white blood cells and platelets. This treatment involves replacing your bone marrow with stem cells donated from somebody who doesn't have sickle cell anaemia. If the transplant is successful, the new bone marrow begins producing healthy red blood cells that do not become crescent shaped (sickle). However, a bone marrow transplant isn't suitable for everyone-ask your doctor if it's suitable for you.
