syngeneic bone marrow transplant
(SIN-jeh-NAY-ik bone MAYR-oh TRANZ-plant)
A procedure in which a patient receives healthy stem cells (blood-forming cells) to replace their own stem cells that have been destroyed by treatment with radiation or high doses of chemotherapy. In a syngeneic bone marrow transplant, the healthy stem cells come from the bone marrow of the patient’s healthy identical twin.
