Fig. 2From: The alveolar epithelial cells are involved in pulmonary vascular remodeling and constriction of hypoxic pulmonary hypertensionEffects of hypoxia on structure of pulmonary and systemic vessels in rats. A Reconstruction of pulmonary and systemic artery were observed by HE staining (a–c) pulmonary artery, bronchial artery and renal artery of normoxic group (d–f) pulmonary artery, bronchial artery and renal artery of hypoxic group. B MT% and MA% of pulmonary and bronchial artery were significantly increased in hypoxic group compared with the normoxic group (a, b) MT% and MA% of pulmonary artery (c, d) MT% and MA% of bronchial artery (e, f) MT% and MA% of renal artery. N:  normoxic group, H: hypoxic group. n = 12, Data are means ± S.D. **P < 0.01 vs. NBack to article page
