Representative photomicrographs showing cells staining positively for the markers studied in bronchial biopsies of control (left), eosinophilic asthma (middle), and mixed/neutrophilic (MIXED) asthma (right) subjects (40× magnification). Arrows indicate positively stained cells. Panel A shows the data of α-SMA 100 μm, panel B shows the basal membrane and panel C shows the number of vessels (CD31⁺ cells). *: p < 0.05; **: p < 0.01. CTRL = control. Data are presented as box plots (25-75th percentiles), and bars (10-90th percentiles) and the horizontal line indicates the mean value in the respective group. The differences between the groups are assessed by Unpaired T test or Mann-Whitney test
