The Correlation between FSTL1 Expression and Airway Remodeling in Asthmatics

Figure 4

Staining of bronchial biopsies of both controls (postmortem samples) and asthmatics and quantitative analysis. H&E stains for (a) controls and (b) asthmatics. Expression of FSTL1 by IHC in (c) controls and (d) asthmatics and (e) quantification of FSTL1 staining. Expression of α-smooth muscle actin by IHC in (f) controls and (g) asthmatics and (h) quantification of α-smooth muscle actin staining. Expression of collagen I by IHC in (i) controls and (j) asthmatics and (k) quantification of collagen I staining. Expression of basement membrane thickness by PASM staining in (l) controls and (m) asthmatics and (n) quantification of basement membrane staining. Expression of fibrosis levels by Sirius red staining in (o) controls and (p) asthmatics and (q) quantification of fibrosis levels. Original magnification ×400. Data is represented as mean ± SD.
