Relaxation of fetal abdominal aortas in response to increasing doses of SNP. A–D: arteries were precontracted with an EC₈₀ concentration of U46619. SNP dose-response curves were compared using two-way ANOVA followed by a Bonferroni post hoc test where appropriate. All data are expressed as means ± SE (n = number of animals). ■ denotes WT male, while ● denotes WT female, □ denotes P0 male, and ○ denotes P0 females.
