Stem Cell Transplantation
Procedure for Stem Cell Transplantation
Stem cells may be The person’s own cells (autologous transplantation) Those of a donor (allogeneic transplantation) If people with cancer are being given their own stem cells, the cells are collected before chemotherapy or radiation therapy, which can damage stem cells. The cells are injected back into the body after the treatment. If the stem cells come from a donor, the recipient is given drugs to suppress the immune system ( Suppression of the Immune System ) before stem cells are transplanted. If the stem cells are intended to replace the blood-forming cells in the recipient's bone marrow, the recipient is given a combination of drugs and radiation treatments to eliminate bone marrow cells that would keep the transplanted cells from surviving.
