A bone marrow transplant, also known as a haemopoietic stem cell transplant, replaces damaged bone marrow with healthy bone marrow stem cells. Bone marrow is a spongy tissue found in the hollow centres of some bones. It contains specialist stem cells, which produce the body's blood cells.
In bone marrow transplant, for adults blood is removed from the body, the stem cells is separated from the other cells in the blood and then the blood is returned to the body. An alternative method is to collect the bone marrow itself by removing stem cells from the hip bone using a special needle and syringe. The extracted stem cell is then transplanted to the suitable recipient.
