China Is Growing Pigs With Human Immune Systems To Use As Organ Donors

[00:00:00]Scientists in China have successfully edited the genes of pig embryos to replace the pig immune system with a functioning human one, creating animals whose organs would not be immediately rejected by a human body after transplantation. And the pigs are being raised as potential organ donors whose hearts, livers, and kidneys could theoretically be transplanted into human patients on demand, and regulators in China have approved the research, while most Western countries are still debating whether it should be permitted.
