Skin culture. A surgeon delicately lifts a square of laboratory-grown human skin from a culture dish in order to give a skin graft to a burns victim. This technique is used to help restore skin to patients whose burns are so extensive that there is little healthy skin left from which to take a graft. Tiny fragments of healthy skin are transferred to a square support like this one, and grown in culture until the skin cells have spread out to cover the support. It takes only three weeks to grow a whole square metre of cultured skin. Photographed at Hopital Edouard Herriot, Lyon, France.
