Single cell RNA-seq to delineate the gene expression of RA chondrocytes
Rheumatoid arthritis (RA) is a common autoimmune joint disease, the pathogenesis of which is still unclear. Cartilage damage is one of the main manifestations of the disease. Chondrocytes are the main functional component of articular cartilage, which is relevant to disease progression. Mechanical loading affects the structure and function of articular cartilage and chondrocytes, but the effect of weight bearing on chondrocytes in rheumatoid arthritis is still unclear. In this study, single-cell RNA sequencing (scRNA-seq) was performed on collected cartilage from the weight-bearing region and non-weight-bearing region of the femur.
