Grafting of skin ulcers with cultured autologous epidermal cells

We treated five adult individuals with six full-thickness chronic ulcerations in the skin caused by venous insufficiency, sickle cell anemia, or surgical wounds. Each patient received applications to the ulcerations of sheets of autologous epidermal cells grown in culture. All patients experienced relief of pain after grafting. Four of the six ulcers healed completely in 21 to 35 days, and three of the four remained healed for up to 2 years. One ulceration recurred within 2 months. Our experience suggests that cultured autologous epidermal grafts can provide continuous covering, relief from pain, and rapid healing of chronic debilitating ulcerations of the skin.
