From: Icariin alleviates osteoarthritis by inhibiting NLRP3-mediated pyroptosis
ICA protected rat against osteoarthritis. a H&E staining and safranin O/fast green staining were used to evaluate cartilage histopathology in OA rats, and immunohitochemical analysis was used to detect NLRP3 in OA rat cartilage tissue. b Statistical analysis of NLRP3 positive rate. All the results were shown as mean ± SD (n = 3), which were three separate experiments performed in triplicate. *p < 0.05 and **p < 0.01
