Figure 3. Comparison of expressions of kinase-insert domain-containing receptor (KDR) and vascular endothelial growth factor (VEGF) in the endometrial tissues of rats in each group at the 9th day after model establishment. A, Representative localization of KDR and VEGF (black arrow) in the endometrium tissues of rats in each group detected by immunohistochemical staining. B, Relative mRNA expressions of KDR and VEGF in endometrium tissues of rats in each group determined by qRT-PCR. C and D, Protein expression of KDR and VEGF in endometrium tissues of rats in each group detected by western blot. Data are reported as means±SD. *P<0.05 compared with the Control group and the Sham group; ^#P<0.05 compared with the Model group and the NC-siRNA group (ANOVA).
