Construction of tissue-engineering skin with carrier of active composite dermal matrix / 中华烧伤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To construct of tissue engineering skin including active composite dermal matrix.</p><p><b>METHODS</b>The human fibroblasts and bovine collagen with type I were inoculated on the surface of porcine acellular dermal matrix (PADM) for construction of active dermal substitute, then epidermal cells were inoculated on the dermal matrix for gas-liquid interface culture. The tissue-engineering skin was observed by histological examinations.</p><p><b>RESULTS</b>The structure of fibroblasts in collagen was intact, which was used to construct composite dermal matrix with PADM. The epithelial structure of tissue-engineering skin was similar to that of normal skin with good cell differentiation. Some phenomena were showed in epidermis: basic layer, stratum spinosum, granular layer and stratum corneum, desmosomes.</p><p><b>CONCLUSION</b>Fibroblasts-Collagen-PADM can be an optimal dermal matrix for construction of tissue-engineering skin.</p>
