Doctors transplant gene-edited pig kidney into living human for 1st time - National:

Doctors in Boston have transplanted a pig kidney into a 62-year-old patient, the latest experiment in the quest to use animal organs in humans.

Massachusetts General Hospital said Thursday that it's the first time a genetically modified pig kidney has been transplanted into a living person. Previously, pig kidneys have been temporarily transplanted into brain-dead donors. Also, two men received heart transplants from pigs, although both died within months.

The patient, Richard "Rick" Slayman of Weymouth, Massachusetts, is recovering well from the surgery last Saturday and is expected to be discharged soon, doctors said Thursday.

Dr. Tatsuo Kawai, the transplant surgeon, said the team believes the pig kidney will work for at least two years. If it fails, Slayman could go back on dialysis, said kidney specialist Dr. Winfred Williams. He noted that unlike the pig heart recipients who were very sick, Slayman is "actually quite robust."

[...] Dr. Parsia Vagefi, chief of surgical transplantation at UT Southwestern Medical Center, called the announcement "a big step forward." But echoing the Boston doctors, he said studies involving more patients at different medical centers would be needed for it to become more commonly available.

The experiment marks the latest development in xenotransplantation, the term for efforts to try to heal human patients with cells, tissues, or organs from animals. For decades, it didn't work — the human immune system immediately destroyed foreign animal tissue. More recent attempts have involved pigs that have been modified so their organs are more humanlike — increasing hope that they might one day help fill a shortage of donated organs.

[...] Pigs have long been used in human medicine, including pig skin grafts and implantation of pig heart valves. But transplanting entire organs is much more complex than using highly processed tissue. The kidney implanted in Slayman was provided by eGenesis of Cambridge, Massachusetts. The pig was genetically edited to remove harmful pig genes and add certain human genes to improve its compatibility with humans.

[...] The Food and Drug Administration gave special permission for Slayman's transplant under "compassionate use" rules.
