The invention solves the problems of poor cell culture effect caused by poor microenvironment creation, poor antibacterial effect and easy degradation of the existing cell culture substrate, and develops a cell culture medium that can more completely simulate the in vivo growth environment of cells and has antibacterial and anti-degradation properties. A functional cell culture matrix, comprising: a mixed powder matrix material, consisting of 60-80wt% collagen type I, 10-30wt% acellular small intestinal submucosa matrix, and 5-10wt% acellular amniotic membrane matrix; a matrix degradation inhibitor, The content is 0.01-1.5wt% of the mixed powder matrix material; the content of the cationic antibacterial material is 0.01-1.5wt% of the mixed powder matrix material. |
