Decreased airway mucus secretion and peribronchial fibrosis in allergen-exposed Ndst1f/fTekCre+ mice. (A and B) Airway mucus secretion in control and allergen-challenged WT and Ndst1f/fTekCre+ mice was examined by PAS staining of lung sections. Images representative of each group are shown. PAS-positive area in airways (5–8 airways/mouse) was quantitated by ImageJ analysis of captured images. (C and D) Peribronchial fibrosis around airways was examined by staining lung sections with Masson's trichrome stain for collagen deposition. Images representative of each group are shown. Fibrotic area was quantitated (2–13 airways/mouse with similar basement membrane length of 660 ± 20 μm) by image analysis using ImageJ. Scale bar in A and C represents 100 μm. Combined data (Mean ± SEM) of n = 5–6 mice/group is shown. *P < 0.01 for comparison of control vs. allergen-exposed mice in B and D and **P < 0.05 in B and <0.01 in D for comparison of allergen-challenged groups.
