OBJECTIVE: To investigate whether icariin, which a widely used pharmacological constituent in traditional Chinese herbal medicine, can be a potential promoting compound for cartilage tissue engineering. DESIGN: Icariin was added into cell-hydrogel constructs derived from neonatal rabbit chondrocytes and collagen type I. The chondrogenic gene expressions and the synthesis of cartilage matrix of the seeded cells were detected by qRT-PCR and Biochemical assay. The effects of icariin-added cell-hydrogel constructs on the restoration of supercritical-sized osteochondral defects of adult rabbit were investigated by histological observation. The cell-hydrogel constructs without Icariin were set for controls. RESULTS: Icariin obviously up-regulate the expressions included aggrecan, sox9, and collagen type II of seeded chondrocytes form 99.7% to 248%. It increases the synthesis of glycosaminoglycan and collagen type II about fourfolds to fivefolds from week 1 to week 4, and accelerates the formation of chondroid tissue in the cell-hydrogel constructs. Even, it improves the restoration efficiency of super critical-sized osteochondral defects in adult rabbit model, and enhances the integration of new-formed cartilage with subchondral bone. CONCLUSIONS: Icariin can be a potential promoting compound for cartilage tissue engineering, and it can be a substitute for the use of some growth factors. The long history and extensive cases of safe use in China, Japan and Korea make it more attractive.
