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