Fig. 5From: Glaucocalyxin A delays the progression of OA by inhibiting NF-κB and MAPK signaling pathwaysThe knee joint of mice was examined histopathologically and immunohistochemically. A Representative HE, SO/FG, p-P65, MM13, and COL2A1 staining photos. The photos were shown at two magnifications: low (×10 magnification, scale 100 µm) and high (×96 magnification, scale 10 µm). B Glaucocalyxin A has been shown to considerably lower the OARSI and Mankin scoresBack to article page
