Fig. 2. Representative photomicrographs illustrating the results of immunohistochemical analysis of PECAM-1 in rat lungs on day 14 (A). Arrows indicate pulmonary vessels stained with PECAM-1. Magnification, 400 ×. Scale bar indicates 50 µm. The number of pulmonary vessels per high-power field (HPF) (B) and pulmonary vascular density (C) are displayed in a bar graph. n = 5-8 per group. *P < 0.05. PECAM, platelet endothelial cell adhesion molecule; BPD, bronchopulmonary dysplasia; V, vehicle; DFX, deferoxamine.
