Human skin culture. View of a petri-dish culture of human skin. This layer of artificial skin has been scored to increase the surface area available for healing onto the site of a skin graft. Human skin cultures are made from a small piece of human skin (such as a biopsy sample). The outer epidermis is separated from the dermis layer underneath and keratinocytes are used to "seed" new growth. Synthetic skin's uses include treatment of severe burns, and in the testing of drugs & cosmetics. Photographed at the Edouard Herriot Hospital, Lyon, France.
