【Abstract】 Chitosan is a partially deacetylated derivative from chitin,which is a natural polysaccharide. As a promising biocompatible,biodegradable and bioactive material,chitosan and its complexes have been studied for use in a number of bone repair applications and bone tissue engineering scaffolds,supporting the growth of chondrocytes or active growing factors. In this paper, recent advances in research and applications of chitosan based composite materials are reviewed for bone repaire and tissue engineering including cartilage and bone.更多还原
