Figure 6
Examination of sulfatases in bronchial biopsies. Bronchial biopsies were stained for the lysosomal sulfatases. Tissue sections from ever smokers (a,c,f,i,l,o) were compared to COPD patients (b,d,g,j,m,p). Panels a and b were stained with hematoxylin (HTX) to label cells and nuclei, whereas the remaining panels were stained with anti-ARSB (c,d), anti-GALNS (f,g), anti-GNS (i,j), anti-IDS (l,m) and anti-SGSH (o,p). All panels are representative images of ever smokers and COPD patients. Graphs (e,h,k,n,q) show quantifications of the different individuals, and each dot represents one subject. Scale bar equals 50 µm.
