Bald? A team of stem cell scientists has made an advance that's a step toward being able to regrow your own natural hair, using samples of your skin.
The scientists took adult human skin cells and transformed them into a particular type of cell that people lose when they lose their hair, called epithelial stem cells. This is the first time scientists have been able to make epithelial stem cells from adult cells. After creating the epithelial stem cells, the scientists transferred them onto the skin of mice, which then grew human skin, human hair follicles, and the beginnings of human hairs.
