Scanning electron microscopy demonstration of cilia in rat intrahepatic bile ducts

Zeitschrift für Anatomie und Entwicklungsgeschichte Aims and scope Submit manuscript

Summary

Numerous cilia have been demonstrated by SEM in cells of rat perilobular and portal bile ducts and ductules. Generally these cilia appear as long, cylindrical evaginations of the plasma membrane. Some of them are so long that, curving and twisting at many points, they cross the ductal lumen. It has been suggested that they may be related to a continual mixing up and propulsion of the bile product down the biliary tree.
