Fig. 2From: Epigenetics of Notch1 regulation in pulmonary microvascular rarefaction following extrauterine growth restrictionEffects of EUGR on postnatal pulmonary vessel density after weaning. Representative lung histology from control (a) and EUGR (b) rats at 3 weeks, stained with von Willebrand factor (a marker of endothelium). Micrographs were obtained at the same magnification (200 ×). Internal scale bar (50 μm). c: the number of von Willebrand factor-stained pulmonary vessels (diameter <50 μm) per high-power field decreased in EUGR rats. Data are presented as mean ± SEM. (n = 5 rats per group). *P < 0.05Back to article page
