Role and application of bone morphogenetic proteins in articular cartilage regeneration / 中国组织工程研究

ABSTRACT

BACKGROUND: Articular cartilage degeneration is the main cause of osteoarthritis. Bone morphogenetic proteins play an important role in cartilage regeneration and repair. OBJECTIVE: To review the research progress of bone morphogenetic protein in the process of articular cartilage regeneration. METHODS: A computer-based online search of PubMed and Elsevier databases was performed using the keywords “bone morphogenetic proteins, BMPs, arthritis, osteoarthritis, OA, cartilage, chondrocyte” in English. A total of 272 papers were retrieved, 96 of which were included in final analysis. Another 27 papers related to concepts were also included. Therefore, 123 papers are finally included. RESULTS AND CONCLUSION: Bone morphogenetic proteins participate in many biological processes including cell proliferation, differentiation, migration, and apoptosis, and play an important role in the formation of bone and cartilage. Bone morphogenetic proteins participate in a variety of signaling pathway cascades by binding to different receptors, which can protect articular cartilage from cartilage destruction caused by inflammation and trauma. Bone morphogenetic proteins alone or in combination with other cytokines can repair cartilage defects improve degenerative lesions, and promote the differentiation and regeneration of articular chondrocytes. However, there are still some practical problems that need to be solved for the widespread use of bone morphogenetic proteins in cartilage regeneration, such as the safety of drug transporters, the lack of effective biological scaffold materials, the optimal dosage and time point of use of biological agents, and their toxic and side effects. Future research will focus on how to solve the above problems. The widespread application of bone morphogenetic proteins will open a new era for targeted treatment of cartilage damage and cartilage degenerative diseases represented by osteoarthritis.
