L-polylactic acid porous microspheres enhance the mechanical properties and in vivo stability of degummed silk/silk fibroin/gelatin scaffold

Cartilage defects are among the most difficult diseases to cure in clinic. Due to the limited regeneration capacity of chondrocytes, cartilage regeneration is very difficult. Tissue engineering is a potential strategy for cartilage regeneration. The choice of scaffold is a key factor for the successful construction of tissue engineering cartilage. In this research, we successfully constructed the silk/silk fibroin/gelatin/polylactic acid porous...
