Fig. 1From: Reduced expressions of connexin 43 and VEGF in the first-trimester tissues from women with recurrent pregnancy lossThe expression of VEGF in chorionic villi and decidua collected from RPL women and control group. a, b The protein expression of VEGF was assessed by immunohistochemistry (magnification X400) and evaluated by IRS scores. The control group exhibited a higher level of VEGF than RPL group. c, d The VEGF protein expression was assessed by Western Blot and the band intensity was evaluated. The VEGF protein is markedly more in the control group than that in the RPL group. e The mRNA level of VEGF was significantly lower in the PRL group than that in the control group. Data were presented as mean ± standard deviation (SD). *: P < 0.05; ***: P < 0.001Back to article page
