If this occurred, the graft could be disconnected from the donor. Pedicle grafts were complicated because they required the donor, for example, a sheep, to be strapped immobile to the patient for several days, during which time the graft would reputedly be vascularized by the recipient. ![]() The grafts were either free skin grafts or pedicle skin grafts. In the 19th century, skin grafts became relatively popular between various animal species and humans ( 8, 9). Genetically modified pigs offer hope of a limitless supply of organs and cells for those in need of a transplant. With the advent of genetic engineering and cloning technologies, pigs are currently available with a number of different manipulations that protect their tissues from the human immune response, resulting in increasing pig graft survival in nonhuman primate models. ![]() Starzl carried out the first chimpanzee-to-human liver transplantation in 1966 in 1992, he obtained patient survival for 70 days following a baboon liver transplant. The first heart transplant in a human ever performed was by Hardy in 1964, using a chimpanzee heart, but the patient died within 2 hours. In 1963–1964, when human organs were not available and chronic dialysis was not yet in use, Reemtsma transplanted chimpanzee kidneys into 13 patients, one of whom returned to work for almost 9 months before suddenly dying from what was believed to be an electrolyte disturbance. Following the pioneering surgical work of Carrel, who developed the technique of blood vessel anastomosis, numerous attempts at nonhuman primate organ transplantation in patients were carried out in the 20th century. ![]() In the 1920s, Voronoff advocated the transplantation of slices of chimpanzee testis into aged men whose “zest for life” was deteriorating, believing that the hormones produced by the testis would rejuvenate his patients. Skin grafts were carried out in the 19th century from a variety of animals, with frogs being the most popular. Between the 17th and 20th centuries, blood was transfused from various animal species into patients with a variety of pathological conditions. In the coming weeks, for example, Nash will take part in a military-funded experiment in which doctors at Boston’s Brigham and Women’s Hospital will try to wean her off the anti-rejection drugs she has been taking since the transplant.Cross-species transplantation (xenotransplantation) offers the prospect of an unlimited supply of organs and cells for clinical transplantation, thus resolving the critical shortage of human tissues that currently prohibits a majority of patients on the waiting list from receiving transplants. military paid for Nash’s full face transplant in 2011 and is underwriting her follow-up treatment at a combined cost estimated in the hundreds of thousands of dollars, in the hope that some of the things it learns can help young, seriously disfigured soldiers returning from war. The Pentagon, though, is watching her recovery closely. She was horribly disfigured, not in combat, but in a 2009 attack by a rampaging chimpanzee. Nash lost her face, eyes and hands after being mauled by a chimpanzee in 2009.Ĭharla Nash never served in the military. The Department of Defense is following Nash’s progress after funding her transplant surgery in 2011. Charla Nash smiled last month as her care worker washed her face at her apartment in Boston. ![]()
