Calycosin contributes to Articular Cartilage Repair. Representative images of immunofluorescence (20X) staining of Sox-9 (a) and Col-2 (c) in the articular cartilage. DAPI stain was used to label the nucleus. Quantitative analysis of the Sox-9 (b) and Col-2 (d) expression demonstrated fluorescence was decreased in the OA group, while enhancement after treated with calycosin. Groups: sham, OA and 50 mg/kg calycosin treatment groups. Data are presented as the mean ± SD
