Abstract:

Osteoarthritis (OA) is a chronic degenerative disease of articular cartilage. Many studies have shown that mesenchymal stem cells can promote the repair of cartilage tissue of OA and improve the joint environment. Some co-cultivation experiments of mesenchymal stem cells and chondrocytes indicate that mesenchymal stem cells may act by secreting some cytokines, and exosomes are an important component of these factors.In vitro experiments confirmed that both exosomes and mesenchymal stem cells derived from mesenchymal stem cells can promote chondrocyte proliferation, maintain chondrocyte phenotype, inhibit chondrocyte apoptosis, promote cartilage extracellular matrix synthesis, and promote chondrocyte migration. In vivo experiments have also shown that exosomes derived from mesenchymal stem cells in OA can repair cartilage, promote cartilage matrix synthesis, and inhibit inflammatory cell infiltration. Compared with mesenchymal stem cell therapy, exosomal therapy alone has the advantages of safety and low cost. This provides a new strategy for the treatment of OA. However, the mechanism of MSCs-EXs in the treatment of osteoarthritis is not clear. This article reviewed the research progress of MSCs-EXs in the treatment of OA.

Key words: Mesenchymal stem cells, Exosomes, Osteoarthritis, Chondrocytes
