Stem Cell Transplantation

A procedure in which a patient receives healthy blood-forming cells (stem cells) to replace their own, when stem cells or bone marrow are damaged or destroyed by disease, as well as some types of cancer, or by high doses of chemotherapy or radiation therapy used to treat cancer. The healthy stem cells may come from the blood or from a donor’s bone marrow or from the umbilical cord blood of a newborn baby. A stem cell transplant may be autologous (use of stem cells from your own bone marrow or blood), allogeneic use of stem cells from someone else, the donor could also be a relative or somebody who isn't associated with you) or syngeneic (use of stem cells from an identical twin). The stem cells within the bone marrow transform into red blood cells, white blood cells and platelets. when these blood cells mature, they go into the peripheral blood (the blood that flows through the body). If the bone marrow is damaged or destroyed, it can’t create normal blood cells. in a stem cell transplant, healthy stem cells are placed in your body to assist your bone marrow start to work properly. The new stem cells make healthy blood cells.
