Scientists at Egenesis Inc. have transplanted kidneys from genome-edited pigs into cynomolgus monkeys that remained functional for long periods after transplantation. The monkeys, whose own kidneys were removed during the surgery, survived for a median of 176 days after receiving one pig kidney. Maximal survival was just over 2 years. The data were published today in Nature. Egenesis CEO Mike Curtis told reporters that the study has achieved the longest survival to date “using clinically translatable immunosuppression … longer survival has been achieved using really aggressive immunosuppression that really isn’t clinically translatable.”
