allogeneic bone marrow transplantation
(A-loh-jeh-NAY-ik bone MAYR-oh tranz-plan-TAY-shun)
A procedure in which a patient receives healthy stem cells (blood-forming cells) to replace their own stem cells that have been destroyed by disease or by treatment with radiation or high doses of chemotherapy. In an allogeneic transplant, the healthy stem cells come from a related donor who is not an identical twin of the patient or from an unrelated donor who is genetically similar to the patient.
