What is Bone Marrow Transplant?
Bone marrow is the soft, spongy tissue inside your bones that makes blood-forming cells (blood stem cells). These cells turn into blood cells including:
- White blood cells to fight infections.
- Red blood cells to carry oxygen throughout the body.
- Platelets to control bleeding.
- Blood-forming cells are also found in the blood stream and the umbilical cord blood.
- A bone marrow transplant is a medical procedure performed to replace bone marrow that has been damaged or destroyed by disease, infection, or chemotherapy.
- This procedure involves transplanting blood stem cells, which travel to the bone marrow where they produce new blood cells and promote growth of new marrow.
- A bone marrow transplant replaces your damaged stem cells with healthy cells. This helps your body make enough white blood cells, platelets, or red blood cells to avoid infections, bleeding disorders, or anaemia.
- Healthy stem cells can come from a donor, or they can come from your own body. In such cases, stem cells can be harvested, or grown, before you start chemotherapy or radiation treatment. Those healthy cells are then stored and used in transplantation.
