Abstract:
BACKGROUND:At present, there are many methods to treat cartilage defects, but none radical y repairs the articular cartilage defects.
OBJECTIVE:To histological y verify the effect of naringin combined with tissue engineering cartilage on the repair of rabbit articular cartilage defects.
METHODS:Rabbit bone marrow mesenchymal stem cells fol owing in vitro proliferation were compounded onto acellular dermal matrix, which was then implanted into rabbit knee cartilage defects. Naringin was also given by lavage. Hematoxylin-eosin staining, Masson trichrome staining, toluidine blue dyeing, type II col agen staining and type X col agen staining were performed in the repaired tissue.
RESULTS AND CONCLUSION:After 8 weeks post-surgery, the defects repaired with the naringin and stem cells composite were turned into milky-white and transparent smooth tissue. The defective tissue which was repaired, was very similar to normal cartilage tissue, with smooth surface. After the histology research, we found that the defect tissue was fil ed with new cartilage tissue. Results indicated that naringin combined with tissue engineering cartilage can promote the repair of articular cartilage defects in rabbits.
