Adventitial Alterations Are the Main Features in Pulmonary Artery Remodeling due to Long-Term Chronic Intermittent Hypobaric Hypoxia in Rats

Pulmonary artery wall: (a) lumen: internal diameter in microns (μm), (b) wall cross-sectional area (CSA) (μm²), and (c) representative confocal images of the pulmonary artery wall of rats exposed to CIH2x2, CH, and NX obtained with a 63x objective. L: lumen, M: media layer, and A: adventitial layer. Values are means ± SEs. Statistical analysis was performed using one-way ANOVA. For wall CSA,   is exposed versus NX.
