(a) Photomicrographs showing immunoreactivity for αsmooth muscle actin, fibronectin and collagen I in bronchial biopsy sections from an asthmatic and a control subject. (b, d and f) Global immunoreactivity for α-SMA, fibronectin and collagen I in sections of bronchial biopsies from controls (n = 23) and asthmatics (n = 18). (c, e, g) Correlations between expression of these proteins and RELM-β+ cells in the biopsies from the asthmatics. Mann–Whitney U-test was used for comparison between groups and Spearman's rank-order method with correction was used for the correlations.
