23 Jul Tissue engineering skin containing living cells and preparation method of tissue engineering skin
Abstract
The invention belongs to the technical field of tissue engineering and particularly relates to tissue engineering skin containing living cells and a preparation method of the tissue engineering skin. The tissue engineering skin comprises an epidermis layer, an imitated corium layer and a corium layer, wherein the imitated corium layer contains keratinocytes, fibroblasts and a bio-scaffold material, and the density ratio of the keratinocytes to the fibroblasts is (0.1-0.2) to 1; and the bio-scaffold material contains gelatin, chitosan, glutamine and hyaluronic acid in a mass ratio of (6-7) to (1.5-2) to (0.5-1) to 1. The tissue engineering skin prepared by virtue of the preparation method has good biocompatibility, plasticity and mechanical strength and can be used for repairing the surface of a wound with a good effect.
