The rationale for xenotransplantation is the short supply of human organs for transplantation.
The first to show that nonhuman organs could be transplanted to humans and function for a significant period of time was Dr. Keith Reemtsma (1925-2000).
At Tulane University in New Orleans, Dr. Reemtsma in 1963 and 1964 gave chimpanzee kidneys to five patients in the first chimpanzee-to-human transplants. The recipients died (of infection) from eight to sixty-three days after receiving a chimpanzee kidney.
Then, in 1964, Reemtsma transplanted a kidney from a chimpanzee to a 23-year-old teacher. She lived with it for nine months until succumbing to overwhelming infection.
Xenotransplantation is synonymous with "cross-species transplantation".
