In patients after extensive burn injury the lack of split thickness skin graft donor sites, and consecutive delay in wound closure are critical factors of morbidity and mortality. In addition limited functional and aesthetic results after transplantation of split thickness skin grafts present a socioeconomic problem. For improved wound closure the aim of this study was the development of a one stage technique for the establishment of a multi layer composite graft, existing of a collagen-GAG-matrix with silicon layer of a two layer synthetic dermal equivalent (DE) with integrated fibroblasts, and ceratinocytes. - In 64 athymic nude mice the evaluation of the multi layer skin grafts potential to re-establish a human epidermis, and high quality dermal structure was performed. In addition to clinical investigations we measured wound contraction, and analyzed histomorphologic, immunohistologic, "in situ hybridisation", and electro microscopic data. - Our results show, that the seeding of DE with human fibroblasts and ceratinocytes as a composite skin graft reproducible enabled a wound healing with an organised human dermis and epidermis within 10 - 15 days. The histological studies of the grafted composite skin grafts in this model showed morphologically a characteristic dermal-epidermal skin structure with a cornifying epithelium, being of human origin ("in situ hybridisation"). Through the co-cultivation of fibroblasts and ceratinocytes in the DE the generation and structural morphology of collagen fibres, and inflammatory reaction in the neodermis is positively influenced, and as a consequence wound contraction significantly reduced. In regard to the early preparation of composite grafts, and the minimal requirements for donor sites - with dependable stable reconstruction of the integument - this technique may present a step forward in the treatment of patients with extensive burns.
