Fig. 6From: Effects of sesamin on chondroitin sulfate proteoglycan synthesis induced by interleukin-1beta in human chondrocytesH&E staining (upper panel) and proteoglycan deposition (lower panel) of HAC pellets on day 21. Chondrocyte mophology and matrices were assessed with H&E staining. The sulfated glycosaminoglycan attached to matix proteoglycans was assessed with safranin-O. Representative sections from one donor are shown at 400× magnificationBack to article page
