Western blot analysis of vascular endothelial growth factor (VEGF) expression in the ovaries of different aged mice. The ovaries were isolated just after the flushing of one-cell embryos. (A) 16-week-old mice. (B) 26-week-old mice. Lane 1: PMSG alone (control). Lane 2: 1 μM SNP + PMSG. Lane 3: 10 μM SNP + PMSG.

3. Figure 2
Immunohistochemistry of vascular endothelial growth factor (VEGF) expression in ovaries of mice aged 26 weeks. The ovaries were isolated just after the flushing of one-cell embryos. Immunostaining with anti-VEGF antibody was usually localized in granulosa cells (Gr), stromal cells (St), and endothelial cells (Ec). The immunostaining intensity was increased after sodium nitroprusside (SNP) treatment. (A) PMSG alone (control). (B) 1 μM SNP + PMSG. (C) 10 μM SNP + PMSG (×100).
