Allogeneic hematopoietic cell transplant is procedure in which a patient receives healthy blood-forming cells (stem cells) from a donor to replace their own stem cells that have been destroyed by treatment with radiation or high doses of chemotherapy.
An allogeneic hematopoietic cell transplant uses a donor's bone marrow or blood. The donor is usually a relative of the patient, although unrelated donors or umbilical cord blood are sometimes used.
Allogeneic stem cell transplantation involves transferring the stem cells from a healthy person (the donor) to the patient's body after high-intensity chemotherapy or radiation. The donated stem cells can come from either a related or an unrelated donor.
