Why wait in line for an organ transplant when you can grow your own? Or if you don’t like your nose, forget plastic surgery–grow a new one. These amazing abilities–once part of science fiction–are now on the way.
A laboratory made a bladder in 1996, and there have been five windpipe replacements so far. One researcher transplanted lab-grown tear ducts and an artery into some of his patients. He has created an artificial nose that he plans to transplant onto a man who lost his own nose due to skin cancer.
