Methods Autologous BMMSC of New Zealand rabbits were acquired and induced into chondrogenic differentiation by adding transforming growth factor-β1 (TGF-β1), dexamethasane and ascorbic acid in vitro. Then the chondrocytes were implanted onto novel polymeric scaffolds made by Poly (dl-lactide-co-glycolide) embedding with chitosan nonwoven cloth. The tissue engineering cartilaginous grafts composed of chondrogenetic BMMSC/scaffolds were finally transplanted into the defects of ear cartilage in rabbits of the experimental group.
