Airway fibrosis in Stat1 +/+ and Stat1 −/− mice exposed to tMWCNTs or rMWCNTs. a Representative photomicrographs taken at 200X magnification of Massons trichrome-stained lung sections showing collagen deposition around airways (arrows) in mouse lungs at 21 days post-exposure. Connective tissue (e.g. collagen) stains blue. Scale bars equal 500 μm. b Area to perimeter (A/P) ratios of mouse lung airway thickness at 21 days post-exposure. (***p < 0.001 or **p < 0.01 compared to control; ***p < 0.001 between tMWCNTs and rMWCNTs)
