VEGF mRNA and protein expression in the peri-ischemic brain tissue in each group. A VEGF (45 kDa) and GAPDH (37 kDa) immunoreactive bands, respectively. Bar graph B depicts significant changes in the optical density of VEGF expression when compared with the corresponding ischemia groups (*P < 0.05). Bar graph C the fold change in VEGF mRNA expression. When compared with ischemia group at 6, 12 and 24 h after MCAO, VEGF mRNA expression in corresponding 10 % HS group is evidently reduced (*P < 0.05). #indicates compared with sham group, P < 0.05. The values are presented as the mean ± SD. Confocal images showing the distribution of GFAP labeled astrocytes (D, G, J, red), VEGF (E, H, K, green), and GFAP labeling overlapping VEGF immunofluorescence can be seen in F, I and L. Note that VEGF expression in astrocytes (arrows) is markedly enhanced at 24 h following MCAO. However, after treatment with 10 % HS, it is noticeably reduced. Scale bars (DL), 50 μm
