Effects 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 < 0.05
