Sheep Liver
‘Humanised’ organs can be grown in animals
It’s bad news, says your doctor. Your liver is failing. So he extracts stem cells from your bone marrow and injects them into a sheep fetus while it is still in the womb. When the sheep is born, much of the animal’s liver will consist of your own cells – ready to be harvested and given back to you.
