23 Jul Tissue engineering skin and preparation method thereof
Abstract
The invention relates to tissue engineering skin and a preparation method thereof. The tissue engineering skin comprises a dermis layer and an epidermis layer, and is prepared from seed cells, cell growth factors and a biological scaffold material according to a biological 3D printing technology. The tissue engineering skin is similar to natural skin, comprises the dermis layer and the epidermis layer, can be produced in batches, can be closely attached to a wound, and has high biocompatibility, the dermis layer contains blood vessels, sweat glands and hair follicles, the shape, size and thickness of the tissue engineering skin can be easily changed, the elasticity and flexibility of the skin after sound healing can be enhanced, and the tissue engineering transplantation success rate can be increased.
