Survival assessment of cultured epidermal allografts applied onto partial-thickness burn wounds

Cultured epidermal allografts (C.E.A.) were applied to 6 partial thickness burns. Biopsies were obtained at intervals between 8-100 days after grafting. In the second week clinical re-epithelialisation of the allografted sites was confirmed histologically. Blood group- and sex-mismatch studies showed that the allografted cells were not present between 8-100 days post-grafting, suggesting that the newly formed epithelium was of host origin.
