Transmission electron micrographs of the tight junction region in ileal enterocytes. Specimens were fixed after exposure to vehicle or sodium caprate (C10) in Ussing chambers. (A) Cell membranes of adjacent cells in close apposition in a tight junction exposed to vehicle (arrows). (B) Tight junction with dilatation (arrows) after exposure to C10. Bars indicate 0.2 μm. C10 induced an increased frequency of dilatations within tight junctions (37%) versus vehicle experiments (5%).
