Title: Fibrovesicular cell in wall of ductus choledocus near duodenum, (rat)
Description: (A, B) Electron micrographs of the fibrovesicular cell (FV) (1). Clenched in between the normal epithelial lining cells these FV cells are found sparsely distributed, their apices protrude into the lumen of the ductus choledocus. They bear bundles of specialized microvilli filled with intermediate filaments as well. The cytoplasm contains heavy bundles (4) of these filaments, Golgi areas, glycogen granules, small electron-lucent vesicles (2) and multivesicular bodies (3). The cells are intimately interdigitated with their neighboring epithelial cells and show well developed junctional complexes (blue arrows).These cells are thought to function a.o. as chemoreceptors or mechanoreceptors. They are mainly found in lining epithelia of glands, tubules with their microvillous protrusions into the lumen.
Keywords/Mesh: ductus choledochus, fibrovesicular cell, mechanoreceptor, chemoreceptor,electron microscopy, POJA collection
