Identical twin transplantation. A physician in
Boston referred a patient to Dr John Merrill. The patient was
dying of renal failure due to chronic glomerulonephritis. The proposed donor
was the patients identical twin. Many scientists, geneticists, surgeons etc
collaborated, the twins were shown to be truely identical and Dr Joseph Murray
performed the surgery. There was a good long term survival for both. The
clear message from this experience was that if the immunoligical barrier could
be overcome a transplanted kidney could give new life to a dying patient.
Peter Medawar gave the Dunham lectures at Harvard, telling the huge and avid
audiences of his studies on tissue immunology.
