“A self-described science nerd is the latest American to get an experimental pig kidney transplant, at a crucial point in the quest to prove if animals organs really might save human lives.

The 54-year-old New Hampshire man is faring well after his June 14 operation, doctors at Massachusetts General Hospital announced Monday…

That’s not the only milestone the Mass General team is marking: A pig kidney has kept another New Hampshire man, Tim Andrews, off dialysis for a record seven months and counting. Until now, the longest that a gene-edited pig organ transplant was known to last was 130 days.

Based on lessons from the New Hampshire men and a handful of other one-off attempts, the Food and Drug Administration approved pig producer eGenesis to begin a rigorous study of kidney xenotransplants.”
