Growing human organs inside other animals has taken another step away from science-fiction, with researchers announcing they have grown sheep embryos containing human cells.
Scientists say growing human organs inside animals could not only increase supply, but also offer the possibility of genetically tailoring the organs to be compatible with the immune system of the patient receiving them, by using the patient’s own cells in the procedure, removing the possibility of rejection.
According to NHS Blood and Transplant, almost 460 people died in 2016 waiting for organs, while those who do receive transplants sometimes see organs rejected.
“Even today the best matched organs, except if they come from identical twins, don’t last very long because with time the immune system continuously is attacking them,” said Dr Pablo Ross from the University of California, Davis, who is part of the team working towards growing human organs in other species.
Ross added that if it does become possible to grow human organs inside other species, it might be that organ transplants become a possibility beyond critical conditions.
