People say a boy should look like his father, which, what? But scientists in Pakistan and Columbia University have found that when it comes to baldness, a father doesn't have to look like his son:
The researchers took papilla cells from seven men who were undergoing hair transplants, cultured them in hanging drops and then injected them into human skin grafted onto mice. Not just any human skin: to put their ideas to a rigorous test, the researchers made the grafts from a type of skin that is normally 100 percent hairless -- foreskins from circumcised infants. A technique that can grow hair on a foreskin has a pretty good chance of growing it on a person's head, they reasoned.New Technique Holds Promise For Hair Loss [nyt]
