Researchers from Harvard University have announced the most extensively gene-edited organism ever, a line of pigs that have had more than 60 genes modified.
It’s about more than just showing off, though; all these changes are aimed at creating a species compatible enough with human biology to allow transplantation of animal organs into human patients. It’s called “xenotransplantation,” and it could be a big part of the future of medicine.

This study could represent a real step toward a solution for a huge proportion of the 125,000 people waiting for an organ transplant in the United States alone.
