Analysis of lung histopathology and alveolar count in mice. a C57BL/6 mice were exposed to hyperoxia at birth and were sacrificed on days 7 and 14. b HE staining of lung tissues from mice in the air and hyperoxia groups (Scale bar = 10 μm; 400×), showed a signifcant decrease in radial alveolar count, and a signifcant increase in mean linear intercept. The representative data from five independent experiments. Data are presented as mean ± SD (n = 5, t-test one-way); *P < 0.05 and **P < 0.01, vs. normoxia group
