IL-25 induced airways EGF expression. A: Representative photomicrographs of epidermal growth factor (EGF) immunoreactivity in lung sections from saline (NS)-, OVA- and IL-25-challenged mice at various time points as indicated (original magnification x20). B: Quantitative analysis of EGF immunoreactivity. The data were collected from 3 independent experiments and are expressed as the mean ± SEM (n = 5 in each group at each time point). *p < 0.05.
