23 Jul Cartilage tissue engineering scaffold material and preparation method thereof
Abstract
The invention discloses a cartilage tissue engineering scaffold material and a preparation method thereof. The scaffold material is a three-dimensional porous structure formed by using sodium alginate and chitosan as a base material, and enabling the carboxyl on a side chain of the sodium alginate activated by activation cross-linking agent to react with amino group of chitosan, wherein molar ratio of the sodium alginate carboxyl to the chitosan amino group is (3:7)-(7:3), and the final product only contains two components, sodium alginate and chitosan. The three-dimensional porous scaffold provided by the invention has good biocompatibility, and is suitable for the cartilage tissue engineering.
