RESUMO
Osteoarthritis is a chronic progressive disease characterized by cartilage degenerative diseases. Due to the lack of vascular supply of articular cartilage and poor regeneration of chondrocytes, it is difficult to repair the cartilage with degenerative wear. A large number of studies have confirmed that bone marrow mesenchymal stem cells, adipose-derived mesenchymal stem cells, umbilical cord blood mesenchymal stem cells, umbilical cord mesenchymal stem cells, synovial mesenchymal stem cells, osteoarthritis joint fluid-derived mesenchymal stem cells, etc. can be effective to relieve osteoarthritis and repair damaged cartilage. Mesenchymal stem cells can directly differentiate into chondrocytes under appropriate microenvironment, and they also have immunosuppressive, anti-inflammatory and paracrine effects. In this paper, the research progress of basic experiments and clinical application of mesenchymal stem cells from different sources in osteoarthritis is reviewed to better promote the research progress of stem cell therapy for osteoarthritis.
