【 摘 要 】

Application of extracorporeal shockwave therapy (ESWT) to the subchondral bone of medial tibia condyle has shown chondroprotective effects of the knee with decreased cartilage degradation and improved subchondral bone remodeling in the osteoarthritis (OA) of rat knee. Recently, transplantation of ex vivo preparations of mesenchymal stem cells (MSCs) to animal or human joints with OA seems to induce therapeutically effective repair because of paracrine responses from host cells including progenitor cells residing within the synovium. This study compared ESWT, Wharton’s jelly mesenchymal stem cells (WJMSCs) and combination of ESWT and WJMSCs therapies for early OA of the rat knee. The results showed ESWT, WJMSCs and combination of therapies significantly improved early OA knee based on analysis of pathological findings, micro-CT and immunohistochemistry (IHC) stain. The combined therapy group increased the bone volume (61.755 ± 1.537), and trabecular thickness (0.215 ± 0.014; P < 0.01) as well as reduced synovitis (1.8 ± 0.37) more than ESWT or WJMSCs individually. However, there were no significant difference in combined ESWT and WJMSCS as shown in the expressions of IGF-1 and TGF-β1 and reduction of the TUNEL activity on OA knee. Furthermore, WJMSCs treatment significantly increased the expression of the type II collagen (22.62 ± 0.84; P < 0.001) when compared with ESWT (6.97 ± 0.54) and ESWT combined with WJMSCs (8.87 ± 0.31) in OA knee. In mechanistic factors analysis, the synergistic effect was observed by ESWT combined with WJMSCs in the expression of RUNX-2, SOX-9 and Collagen Xα1 on OA knee. Our results provided the innovative information of ESWT, and WJMSCs in the treatment of early osteoarthritis of the knee in rats.
