Expression of RAMP2 in OA from normal pregnancy and FGR pregnancy.

(A) The mRNA expression of RAMP2 in the omental arteries from normal pregnancy (n = 15) and FGR pregnancy (n = 6). Expression of RAMP2 mRNA was normalized to the expression of GAPDH mRNA. Data are presented as mean ± SEM. *P < .05 vs. normal. (B) Immunofluorescent localization of RAMP2 (red) in sections of the OA from normal and FGR pregnancy. CD31 (green) was used for endothelial staining, IgG for negative control (not shown). and DAPI (blue) was used for nuclear staining (n = 3; magnification, 200×).
