From: Morphologically intact airways in lung fibrosis have an abnormal proteome
Cilia expression in the fibrotic honeycomb airway cells. Two non-fibrotic control and 4 fibrotic patient specimens were stained for alcian blue/periodic acid Schiff’s (AB/PAS) or immunostained for TUBA4A (a marker of cilia). Shown are representative images for A non-fibrotic control airway, B fibrotic uninvolved airways, and C fibrotic honeycomb airways. Note that regions of mucin positivity (red arrows) are absent of cilia (black arrows) in the fibrotic honeycomb airway cells. Scale bar represents 100 microns
