New techniques for the grafting of cultured human epidermal cells onto athymic animals

Abstract

Cultures of human epidermal cells may be used to generate epidermis on athymic recipients. We describe two novel techniques for grafting such cultures. Both techniques permit the generation of typical human epidermis within 7 d. Both techniques result in less graft contraction than conventional grafting, and there is no difficulty in distinguishing the human epidermis generated by the graft from the epidermis of the recipient animal. Starting with a single human biopsy, epidermis may be generated on a great many experimental animals; such grafts should therefore provide uniform material for investigation of the properties of human epidermis. © 1988.
