Establishment of the OA rat model and confirmation of hub gene expression. A, B Representative images of HE staining and Safranin O/fast green staining for articular cartilage (magnification: × 100; scale bar: 100 μM). C OARSI scores of cartilage specimens from control and OA groups. D Serum levels of inflammatory factors (TNF-α, IL-8, and IL-6) were detected by ELISA. E RT-qPCR was used to measure hub gene expressions in OA rats. ***P < 0.001 versus control group
