Successful Donor Cell Engraftment in a Recipient of Bone Marrow from a Cadaveric Donor

A 12-year-old male with acute lymphocytic leukemia received donor bone marrow from his histocompatible father whose marrow was harvested 40 minutes postmortem after he suffered a myocardial infarction. The marrow was stored in liquid nitrogen for 17 days prior to infusion into the recipient. Trypan blue viability was >99% for the fresh marrow. Progenitor cell assays revealed that 20% of the CFU-MIX, 16% of the BFU-E, 10% of the CFU-E, and 17% of the CFU-GM were spared during the cryopreserva-tion period. Posttransplantation, the recipient had a leuko- cyte count >103/µL by day 26. Southern blotting analysis documented the donor origin of the peripheral blood mononuclear cells and granulocytes isolated 46 days posttrans-plantation. Unfortunately, the patient died of complications relating to graft-v-host disease 67 days following transplantation. This case demonstrates the feasibility of cadaveric marrow as a source of donor cells and is the first reported case of documented leukocyte engraftment in a recipient of cadaveric marrow.
