Electron microscopic evidence for a muscle layer in the wall of the terminal hepatic venule in the rat

Electron microscopically smooth muscle cells could be detected in the walls of the terminal hepatic venules of the rat liver. These muscle cells are double layered in the following venous channels, the intercalated veins. It is supposed that these smooth muscle cells play an important role as outlet...

Summary:Electron microscopically smooth muscle cells could be detected in the walls of the terminal hepatic venules of the rat liver. These muscle cells are double layered in the following venous channels, the intercalated veins. It is supposed that these smooth muscle cells play an important role as outlet sphincters of the liver sinusoids. Furthermore, fenestrations could be found in the endothelial lining of terminal hepatic venules.
