Histological analysis of vascular abnormalities in lung from silica-treated mice. Mouse lung were stained with Mason’s trichrome and imaged using 400× magnification. Panel a-c: representative images of pulmonary arteries from control mice. Panel d-i: images of pulmonary arteries with different vascular abnormalities. Vascular wall thickening (d-f); inflammatory cells and collagen deposition around pulmonary arteries (g-h); endothelial proliferation (i)
