Thousands of Americans each yearfor a transplant, and many experts acknowledge there never will be enough human donors to meet the need.

Animals offer the tantalizing promise of a ready-made supply. After decades of failed attempts, companies including Revivicor,and Makana Therapeutics are engineering pigs to be more humanlike.So far in the U.S. there have been four “compassionate use” transplants, last-ditch experiments into dying patients — two hearts and two kidneys. Revivicor provided both hearts and one of the kidneys. While the four patients died within a few months, they offered valuable lessons for researchers ready to try again in people who aren’t quite as sick.

Now the FDA is evaluating promising results from experiments in donated human bodies and awaiting results of additional studies of pig organs in baboons before deciding next steps.They’re semi-custom organs — “we’re growing these pigs to the size of the recipient,” Ayares noted — that won’t show the wear-and-tear of aging or chronic disease like most organs donated by people.

Transplant surgeons who’ve retrieved organs on Revivicor’s farm “go, ‘Oh my god that’s the most beautiful kidney I’ve ever seen,’” Ayares added. “Same thing when they get the heart, a pink healthy happy heart from a young animal.”
