Cell identification and cell percentages of the primary ATE cells. The cell types of the cultured cells were identified by immunocytostaining. β-tubulin IV, ciliated cells; mucin 5AC, goblet cells; E-cadherin and ZO-1, epithelial cells; K14 and GSI-B4, basal cells; smooth muscle actin (SMA), smooth muscle cells; vimentin, fibroblast cells. The percentages of individual cell types among the ATE cells are illustrated. The data represent triplicate experiments that analyzed at least 500 counted cells. Scar bar, 25 μm.
