Fig. 2From: Raloxifene retards the progression of adjacent segmental intervertebral disc degeneration by inhibiting apoptosis of nucleus pulposus in ovariectomized ratsVan Gieson (VG) staining and histological scores of L5–L6 segments in each group. A Intervertebral disk degeneration (IVD), nucleus pulposus (NP) (notochord cells are indicated by the blank arrow, mucoid degeneration of NP is indicated by the thin arrow, and the doublets of chondrocyte-like cells are indicated by the large arrow), and endplate (EP). The double arrow represents the thickness of EP. CEP, cartilage endplate; VP, vertebral physis; B, bony tissues. B Histological scores. #p < 0.01,*p < 0.05Back to article page
