A red blood cell transfusion or a platelet transfuson can help some patients with low blood counts. is a safe and common procedure. Most people who have a bone marrow failure: A condition that occurs when the bone marrow stops making enough healthy blood cells. The most common of these rare diseases are aplastic anemia, myelodysplastic syndromes (MDS) and paroxysmal nocturnal hemoglobinuria (PNH). Bone marrow failure can be acquired (begin any time in life) or can be… disease like aplastic anemia: (ay-PLASS-tik uh-NEE_mee-uh) A rare and serious condition in which the bone marrow fails to make enough blood cells - red blood cells, white blood cells, and platelets.

They enter the patient's bloodstream through an intravenous (IV) needle and make their way into the bone marrow. The donor cells are called a graft. There are three sources of stem cells - bone marrow, cord… or hematopoietic stem cell transplant (HSCT).The procedure replaces unhealthy blood-forming stem cells: Cells in the body that develop into other cells. There are two main sources of stem cells. Embryonic stem cells come from human embryos and are used in medical research. Adult stem cells in the body repair and maintain the organ or tissue in which they are found. Blood-forming (hemapoietic) stem… with healthy ones and offers some patients the possibility of a cure. But for many patients, a BMT is not an option due to the risks and potential long-term side effects as an "imperfect cure".
