Livers revitalized from a bag like this full of human cells. Ears grown from living cartilage. Thumbs, sculpted from coral. Needed parts and vital organs, from the lab and into bodies. Sound too good to be true, or more like science fiction? lt's closer to reality than you might think, and it's next on 21st Century Medicine's Regenerating Life. What if you were so severely burned that you couldn't recognize your own face in the mirror, but a skin patch made of discarded human cells could painlessly restore it to normal? Suppose you were a promising young athlete and the cartilage in your knee was damaged beyond repair, but with the help of a serum-based growth solution it was possible to grow new cartilage? lmagine breaking a bone that refused to heal and facing a life of pain and disability, but then being offered an experimental putty filled with protein to help you heal. Or what if you needed a new liver, but instead of a major transplant doctors simply repaired your old one?
