23 Jul Tissue engineering autologous complex skin and its preparation method
Abstract
A tissue engineered auto compound skin is disclosed. The compound skin consists of auto dermal cell layer attached to the fibrin bio-stent and auto epidermic cell layer. The preparation process: amplifying and differentiating epidermis stem cell and corium fibroblast, implanting, culturing epidermis cell on the corium fibroblast containing fibrin bio-stent, and constructing tissue engineered auto-compound skin in vitro. The tissue engineered compound skin can be applied in the preparation of bio-material for skin transplantation. The advantages of the present invention lies in that it has no rejection action, highly survival rate, long tissue survival period and the wound surface can be repaired quickly with a favorable healing up effect and normal appearance.
