Suppression of NO production impairs smooth muscle cell development and recruitment. (A) IHC staining against smooth muscle α-actin (SM α-actin) to visualize the vascular smooth muscle cell development at E18.5. (B) Relative expression of SM α-actin in A quantified which based on the IOD (n = 4 mice per group, unpaired t-test). IHC staining against SM α-actin at E20.5 and quantification displayed in (C,D) (n = 4 mice per group, unpaired t-test). IHC staining against MHC at E20.5 and quantification displayed in (E,F) (n = 4 mice per group, unpaired t-test). Scale bar: 60 μm. Data presented as means ± SEM, * P < 0.05.
