Shown are the pedestals stained to reveal EPEC cells (blue), actin bundles (red), and zonula occludens-1 (green) in EPEC-infected HeLa cells. It is notable that zonula occludens-1 is stained most in the distal part of the structures, suggesting that a certain factor(s) at the region mediates the particular localization.
