For growing regular organs like livers etc it seems like a great idea. We already slaughter these animals to eat, so slaughtering them to save lives can hardly be protested.
However, this exerpt does raise some flags..I don't think anyone wants sheep running around with the mental capacity of humans. Of course, we'd never know!
Quote:When the lamb is born, two months later, it would have a liver, heart, lungs and brain that are partly human and available for transplant.
Quote:Prof Zanjani said: "Transplanting the cells into foetal sheep at this early stage does not result in fusion at all."
