Figure 3

Optical images of the cytoskeleton organization in Caco-2 cells (A) and M cells (B–D). F-actin was stained with rhodamine-phalloidin. Caco-2 cells depict a well-differentiated brush border indicated by the intense red F-actin staining. In contrast, M cells show a reduced/absent brush border indicated by a reduced F-actin labeling (B–D) (scale bar = 20 µm).
