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.”

The blessing of the animals is a long-time Catholic tradition celebrated on January 17. On this day, Mexican Catholic congregations and priests welcome pups, cats and the occasional parrot on the feast day of St. Anthony the Abbot, considered the patron saint of animals.A few parishioners dress up their beloved pets with sweaters or scarves. But all pray to God and their four-legged friends’ patron to keep them healthy and safe.

Karla Flores feels as if Lana, her 11-year-old dog, was a true blessing. Someone abandoned her as a newborn outside her home on Dec. 12, when millions of Mexican Catholics celebrate“We found her next to her mom and little brothers inside a box,” Flores said. “We rescued them and gave up most of them for adoption, but we kept her and her mom.”
