“Mr. Faucette’s last wish was for us to make the most of what we have learned from our experience,” Dr. Bartley Griffith, the surgeon who led the transplant at the University of Maryland Medical Center, said in a statement.Attempts at animal-to-human organ transplants — called xenotransplants — have failed for decades, as people’s immune systems immediately destroyed the foreign tissue. Now scientists are trying again using pigs genetically modified to make their organs more humanlike.

Faucette, a Navy veteran and father of two from Frederick, Maryland, had been turned down for a traditional heart transplant because of other health problems when he came to the Maryland hospital, out of options and expressing a wish to spend a little more time with his family.In mid-October, the hospital said Faucette had been able to stand and released video showing him working hard in physical therapy to regain the strength needed to attempt walking.Cardiac xenotransplant chief Dr. Muhammad Mohiuddin said the team will analyze what happened with the heart as they continue studying pig organs.

Many scientists hope xenotransplants one day could compensate for the huge shortage of human organ donations. More than 100,000 people are on the nation’s list for a transplant, most awaiting kidneys, and thousands will die waiting.A handful of scientific teams have tested pig kidneys and hearts in monkeys and in donated human bodies, hoping to learn enough for the Food and Drug Administration to allow formal xenotransplant studies.

ATLANTA (AP) — Black women around the world gather in salons, dorm rooms and living rooms for hours at a time to get synthetic braids put in their hair. But they’re wondering if the convenience and fashion benefits are being outweighed byThe pig zone is surrounded on all sides by security and mechanical systems that shield the animals. Outside air enters through multiple filtration systems. Giant vats hold backup supplies of drinking water. Standing over the pig rooms, VonEsch showed how pipes and vents were placed to allow maintenance and repair without any animal contact.

It will take years of clinical trials to prove whether xenotransplantation really could work. But if it succeeds, United Therapeutics’ plan is for even larger facilities, capable of producing up to 2,000 organs a year, in several places around the country.The field is at a point where multiple kinds of studies “are telling us that there’s no train wrecks, that there’s no immediate rejection,” Ayares said. “The next two or three years are going to be super exciting.”
