23 Jul Preparing method of heterogeneous acellular dermal matrix substrate with good biocompatibility
Abstract
The invention relates to a preparing method of a heterogeneous acellular dermal matrix substrate with good biocompatibility. The method concretely comprises the following steps of (1) split thickness skin graft preparation; (2) epidermis and dermis separation; (3) acellular processing; (4) cross linking; (5) virus inactivation; (6) refining; (7) Co-60 irradiation sterilization. The ecellular tissue engineering materials obtained by the method provided by the invention has the advantages that the toxicity is stable, and the cell compatibility is better.
