SMSC-140-Exos prevent OA (A) Sections of femoral condyle (n = 10 for each group) were stained using Safranin-O & fast green (Scale bar: 500 μm). Photomicrographs of femoral condyle sections (n = 10 for each group) stained using anti-type II collagen, anti-aggrecan or anti-type I collagen as primary antibodies (Scale bar: 50 μm). (B) Statistical results of chondrocytes counted in randomly-selected high magnification fields and the result of statistical analysis of OARSI score in each group. *P < 0.05 compared to Normal. (C) Diagram illustrating the proposed mechanism of action of SMSC-140-Exos in OA.
