A woman in the US state of Alabama has passed a major milestone to become the longest-living recipient of a pig organ transplant—healthy and full of energy with her new kidney for 61 days and counting, AP reports.
“I’m superwoman,” Towana Looney told AP, laughing about outpacing family members on long walks around New York City as she continues her recovery. “It’s a new take on life.”
Only four other Americans have received hugely experimental transplants of gene-edited pig organs—two hearts and two kidneys—and none lived more than two months.
Dr. Robert Montgomery of NYU Langone Health, who led Looney’s transplant, called Looney’s kidney function “absolutely normal.”
Doctors hope she can leave New York—where she’s temporarily living for post-transplant checkups—for her Gadsden, Alabama, home in about another month.
Scientists are genetically altering pigs so their organs are more humanlike to address a severe shortage of transplantable human organs. More than 100,000 people are on the US transplant list, most who need a kidney, and thousands die waiting.
Pig organ transplants so far have been “compassionate use” cases, experiments the US Food and Drug Administration allows only in special circumstances for people out of other options.
