In January 2022, researchers genetically engineered a pig heart to resist transplant immune rejection in a human patient (see BioNews 1128).
However, the man who received the first-in-human pig heart transplant died two months later (see BioNews 1144).
Now, two genetically modified pig hearts have been successfully transplanted into two brain-dead people by surgeons at New York University.
According to Reuters, the hearts functioned normally, with no signs of rejection during the three-day experiments in June and July.
