Figure 3. OVX impairs the vasculature in trabecular bone. (A) Images of immunofluorescence staining for CD31 (red) in distal femoral metaphysis from sham-operation and OVX rat. GP: growth plate. Scale bar: 200 μm. (BD) The concentrations of PDGF-BB VEGF and TGF-β in serum were determined by ELISA. p values of less than 0.05 were considered statistically significant (* p <0.05, ** p <0.01, *** p <0.001). n = 12/group.
