In 2015, a baboon was kept alive with a pig heart for 945 days, still a record. That comforts me a lot knowing that he helped other people.. (The University of Alabama at Birmingham did a similar operation in between.) The method involves using gene-editing to "knock out" three genes from the donor pig's genome that activate a rapid immune system response in the human recipient, and adding six human genes that aid the organ's acceptance. Baby Fae lived for only twenty days afterward. Doctors have long pursued new ways to meet the nations need for transplant organs. David. COVID-19 at Three: Who Got the Pandemic Right?

The median survival time following a heart transplant is about twelve years; for kidney transplants, that number is nearing twenty years. Zoe A. Stewart-Lewis, Robert A. Montgomery, Bonnie E. Lonze and Jeffrey Stern. Xenotransplantation - implanting organs from one species to another - is a growing field and scientific advances could help address organ transplant shortages. Transplants of human organs and of pig organs may seem like very different procedures, but the problem of rejection is the central issue in both cases. The heart used in the transplant came from a pig with several genetic modifications, including some to knock out genes that trigger the human immune system. We dont eat pork or talk about pork.

He had been deemed ineligible for a human transplant, a decision that is often taken by doctors when the patient is in very poor health. But doctors say this new transplant is a breakthrough because the donor pig had undergone gene-editing to remove a specific type of sugar from its cells that's thought to be responsible for previous organ rejections in patients.
