A bile canaliculus (BC) is formed from the plasma membranes of adjacent hepatocytes sealed off by tight junctions (J). Rho kinase, myosin-II, and p42/44 MAPK control extracellular matrix-mediated apical bile canalicular lumen morphogenesis in HepG2 cells. Vauthier V, Ben Saad A, Elie J, Oumata N, Durand-Schneider AM, Bruneau A, Delaunay JL, Housset C, Aït-Slimane T, Meijer L, Falguières T. Sci Rep. 2019 Apr 30;9(1):6653. doi: 10.1038/s41598-019-43111-y. 2006 Jul;17(7):3291-303. doi: 10.1091/mbc.e06-01-0067. The canaliculi function to secrete and concentrate components of the bile and to transport the bile out of the interior of the hepatic parenchymal tissue to the epithelium-lined bile ducts. NLM 3) which are endothelial-lined channels that run between the cords of hepatocytes, arranged radially from the central vein. The bile canaliculi drain through short bile ductules (cholangioles), partially lined by cuboidal epithelial cells, to bile ducts, lined with simple cuboidal epithelium, which course along with branches of the portal vein and hepatic artery in portal tracts. Later, immature bile canaliculi were discerned that were located asymmetrically between adjacent cells. Biliary passages start with tiny bile canaliculi between hepatocytes. Bile is produced exclusively by hepatocytes and secreted into the bile canaliculi, which are gutter-like structures between two or three adja-cent hepatocytes in the hepatocytic plates (11). Mature bile canaliculi appeared between adjacent cells 48 hours after the release of the nocodazole block. Alcohol Clin Exp Res. Epub 2016 May 12. Bile canaliculi (histological slide) These canals are lined by both hepatocytes and cuboidal cholangiocytes. preformed and assembled in the intracellular microvilli-. The bile ductule is lined by simple cuboidal to columnar epithelium and drains exocrine secretions of hepatocytes from the liver. These drain into bile collecting ducts lined by simple cuboidal or columnar epithelium, known as the canals of Hering, which in turn drain into the bile ductules B. The canalicular surface is lined by glycoprotein I, which cross reacts with polyclonal carcinoembry-onic antigen (CEA), an immunohistochemical The intrahepatic ducts, cystic duct, and the common bile duct are lined by a tall columnar epithelium.  |  Decribe the path of bile to the main hepatic ducts. Epub 2005 Oct 18. HHS The bile canaliculi empty into a series of progressively larger bile ductules and ducts, which eventually become common hepatic duct. The apical domain consists of the bile canalicular structures. A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein..  |  A. As the bile canaliculi join near the periphery of the lobules, they form into larger canals (also known as the Canals of Hering). Experimental analysis of canaliculus development and function has been undertaken in a number of experimental systems, ranging in complexity from intact animals to isolated hepatocyte cell cultures.  |  Are bordered directly by endothelial cells b. J Cell Sci. Developing hepatic cords were lined by a laminin–positive basement membrane and by CD31-positive sinusoid endothelial cells (Figure 4E and 4F). Development and maintenance of bile canaliculi in vitro and in vivo. Each portal triad contains one or several bile ductules. Intracellular sites involved in the biogenesis of bile canaliculi in hepatic cells. Bile canaliculus (plural:bile canaliculi; also called bile capillaries) is a thin tube that collects bile secreted by hepatocytes. This site needs JavaScript to work properly. This article summarizes what is known about how the functional components of the canaliculus develop and the directions that current experimental approaches are leading in analyzing this process. 2015 Mar 17;10(3):e0119502. We used HepG2 cells, a hepatoma cell line to study the formation of the bile canaliculi in the apical part of the cells. The bile canaliculi empty directly into the Canals of Hering.

Mol Biol Cell. 2005 May;320(2):243-9. doi: 10.1007/s00441-004-1073-5. Bile ductules from portal triads course through the liver and connect to form increasingly larger caliber structures, bile ducts, that are lined by short to tall columnar epithelium. Structural analogues of roscovitine rescue the intracellular traffic and the function of ER-retained ABCB4 variants in cell models. 2010 Oct 1;123(Pt 19):3294-302. doi: 10.1242/jcs.068098. These approaches each have inherent advantages and disadvantages for studying the various aspects of canaliculus development and function. eCollection 2015. Outside the porta hepatis, the main hepatic duct joins the cystic duct from the gallbladder to form the common bile duct, which drains into the duodenum. Evidence from spontaneous contractions in vitro. 2011 Jan 25;108(4):1403-8. doi: 10.1073/pnas.1018376108.
