23 Jul Biological sponge based on acellular dermal matrix and preparation method thereof
Abstract
The invention discloses a biological sponge based on acellular dermal matrix and a preparation method thereof. The biological sponge is made of an acellular dermal matrix as a raw material, and Ca2<+>and fa-PEG are used for cross-linking. The biological sponge prepared by the invention has a porous structure, has pores which communicate with one another, and has a three-dimensional structure similar to human skin tissue, can enable body tissue cells to grow rapidly, has good plasticity, and can be prepared into different shapes as needed so as to meet the needs. The biological sponge of the invention is an advanced tissue engineering scaffold material, contains rich growth factors, has good biocompatibility, is more conducive to the growth of Sertoli cells, can not only be used for woundrepair, but also is an excellent tissue engineering skin scaffold material, and can be used for repairing skin defects and preparing tissue engineering skin.
