The surgical applications and implications of cultured human epidermis: a comprehensive review.
Replacement of skin has long been the ultimate task for surgeons facing skin-resurfacing challenges such as thermal burns and chronic ulcerations. Autologous skin grafts have been the "gold standard" for wound closure, but in patients who are massively burned, the availability of normal skin is the limiting factor. In the past 15 years the technique of in vitro cultivation of human epidermis has been developed in an attempt to deal with the problem of extensive skin loss. Although the technique is costly and arduous, grafting patients who are severely burned with cultured epidermal autografts has proved to be a life-saving measure where few alternatives exist. Cultured allografts have promoted rapid healing and pain relief in patients with chronic ulcers. Although longer follow-up is necessary, recent evidence suggests that cultured epidermis provides a wound cover that is just as durable and esthetically acceptable as conventional split-thickness skin grafts. This article reviews the development and applications of epidermal cell culture.
