Fig. 2From: FGF2 is overexpressed in asthma and promotes airway inflammation through the FGFR/MAPK/NF-κB pathway in airway epithelial cellsFGF2 was overexpressed in asthmatic lungs compared with non-asthmatic patients. a Representative immunofluorescence images for FGF2 in the lung sections to show the overexpression of FGF2 in asthmatic airway epithelium, compared with non-asthmatic patients (n = 5, scale bar = 20 μm). b Representative immunofluorescence images for FGF2 and pro-SPC in the lung sections to show FGF2 overexpression in asthmatic alveolar areas (n = 3–5, scale bar = 20 μm). Data are represented as mean ± standard error of the mean. *P < 0.05. FGF2 fibroblast growth factor 2, epi epithelial, pro-SPC pro-surfactant protein CBack to article page
