Human skin grown in laboratory
Scientists from King’s College London have grown human skin from stem cells which they say more closely resembles actual human skin than anything created in a lab before.
Unlike previous efforts to create human skin in which scientists used skin cells removed by biopsy, this time, researchers used reprogrammed skin cells, which provide an unlimited supply of the main type of cell in the epidermis. The researchers grew the skin cells in a low humidity environment, which allowed them to create a permeable barrier similar to that of true skin.
That stopped moisture from escaping and microbes from entering. The researchers said that this new model can be easily reproduced and used for a wide range of medical purposes. In particular, it could provide a cost-effective alternative to testing drugs and cosmetics on animals.
