Hybrid organs raise prospect of fully human body parts being grown inside animals for transplants
Scientists have grown humanised kidneys in pigs, raising the prospect of human organs being grown inside animals.
The research involved creating human-pig chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing embryos were shown to have kidneys that contained mostly human cells, marking the first time that scientists have grown a solid humanised organ inside another animal.
