Fig. 4From: Icariin-conditioned serum combined with chitosan attenuates cartilage injury in rabbit knees with osteochondral defectICS-CSSH promoted the secretion of glycosaminoglycans (GAG) and Collagen II expression in the osteoarthritis knee. A ICS-CSSH promoted GAG secretion in the articular fluid (n = 6, mean ± SEM). *P < 0.05, ***P < 0.001 versus indicated groups. B ICS-CSSH improved Collagen II expression in rabbit knees in vivo through immunohistochemical observation. Scale bar, 100 μmBack to article page
