Molecular mechanism of icariin effects on articular chondrocytes, subchondral bone and synovium in the treatment of osteoarthritis / 中国组织工程研究

ABSTRACT

BACKGROUND: Icariin is the main effective component of Epimedium, which functions to tonify the kidney, and strengthen tendons and bones. In recent years, a large number of studies have found that icariin plays a significant role in the treatment of osteoarthritis. OBJECTIVE: To review the research progress in the molecular mechanism of icariin in the treatment of osteoarthritis. METHODS: The first author used “Icariin, Osteoarthritis, Cartilage, Subchondral bone, Synovial membrane, synovium, Inflammation" as search words in English and Chinese to search PubMed, CNKI, WanFang, and VIP databases. According to the inclusion criteria and exclusion criteria, 42 articles were included for final analysis. RESULTS AND CONCLUSION: Icariin can promote the cartilage differentiation of bone marrow mesenchymal stem cells and enhance the proliferation of cartilage cells and osteoblasts, to inhibit the degradation of cartilage extracellular matrix, reduce the activity of osteoclasts and alleviate synovial inflammation caused by inflammatory factors. It is an effective treatment for osteoporosis. However, the optimal effective dose and concentration safety of icariin still need a large number of experimental studies. Currently, most of the experiments are still in animal and tissue cell experiments. Numerous clinical studies are needed to continue to explore its specific mechanism in order to provide evidence-based medical evidence for icariin in the treatment of osteoarthritis.
