PTX3 expression in lung veins and venules. (A) Quantification of PTX3 expression in endothelial cell layer of lung blood vessels. The amount of PTX3 expression measured in the acute (3 days), subacute (4 weeks) or chronic (24 weeks) experiment was normalized for the length of internal perimeter of the vein and expressed as mean ± SEM (N = 8 animals/group; * p < 0.05 and ** p < 0.01). Photomicrographs of PTX3 immunostained veins in lung tissue upon (B) 3 days air, (C) 3 days CS, (D) 4 weeks air, (E) 4 weeks CS, (F) 24 weeks air and (G) 24 weeks CS exposure. (magnification: 200×).
