Figure 3From: Transformation of human bronchial epithelial cells alters responsiveness to inflammatory cytokines Cytokine-specific signalling in bronchial epithelial cells. Paired primary cultures of normal and metaplastic epithelial cells (EC-14) were treated for 15 min with the factors listed at the bottom. The relative levels of phosphorylated STAT1, STAT3, EGFR and ERK, as well as the total STAT3 and ERK, were determined by immunoblotting.Back to article page
