Fig 1. ErbB receptors in rat fetal lung fibroblasts and alveolar epithelial type II cells.
A: Representative blots of phosphorylated (upper panel) and total ErbB1, ErbB2, ErbB3 and ErbB4 (middle panels) and actin (lower panel) in female fibroblasts (left side) and alveolar type II cells (right side). B: Densitometric analysis of ErbB receptor protein amounts. Values represent the ratio of receptor protein to β actin, Mean±SEM, N=7, *: P<0.05.
