TFDG protects DMM-induced cartilage from degradation. (a and b) The rats of joint sections were stained by HE and safranin O/fast green. (c and d) The COLII and Nrf2 protein expressions in cartilage were determined by immunohistochemistry staining. (e) The OARSI scores of cartilages in different groups. (f and g) The Nrf2 and COLII positive cells were quantified. The bar graph shows the of data (). , , , and . Scale bar: 100 μm.
