Dermis culture. A petri dish culture of dermis, part of human skin, seen with a contraction of cells in the centre of the culture. Dermis is known as the true skin: it is the thick layer of living tissue that lies beneath the epidermis. It consists mainly of loose connective tissue within which are blood vessels, nerve endings, sweat glands and hair follicles. Artificial skin is cultured in the laboratory by "seeding" a sample of human dermis with epithelial cells. Photographed at the Laboratory of Dermatology, Creteil, France.
