Small cholangiocyte
Webbintracellular mechanisms regulating small cholangiocyte proliferation are undefined. There-fore, we sought to address the role and mechanisms of action by which phenylephrine, an a 1-adrenergic agonist stimulating intracellular D-myo-inositol-1,4,5-triphosphate (IP 3)/Ca 21 lev-els, regulates small cholangiocyte proliferation. Webb1 feb. 2011 · Small cholangiocytes proliferate via activation of calcium (Ca2+)‐dependent signaling in response to pathological conditions that trigger the damage of large cyclic adenosine monophosphate–dependent cholangiocytes. Although our previous studies suggest that small cholangiocyte proliferation is regulated by the activation of …

Webb27 nov. 2003 · Aims: We have shown that large and small cholangiocytes, which reside primarily in large and small intrahepatic bile ducts, respectively, have different functions and responses to injuries. However, there are no systematic studies of the molecular differences between small and large cholangiocytes, which would explain cholangiocyte … WebbThis cell line is aneuploid, will form colonies in soft agar and retains small cell carcinoma morphology and ultrastructure as well as APUD cell characteristics. The cells grow in aggregates, thus cell counts are not accurate. The cells stain positively for cytokeratins. The line can be adapted to grow in shaker flask or spinner flask systems. The N-myc …

Consistent with damage of large ducts, we detected cytochrome P …
Cholangiocytes act through bile-acid independent bile flow, which is driven by the active transport of electrolytes. In contrast, hepatocytes secrete bile through bile-acid dependent bile flow, which is coupled to canalicular secretion of bile acids via ATP-driven transporters. Visa mer Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and carbonate-secreting in larger bile ducts approaching the porta hepatis and … Visa mer Active scientific investigation of cholangiocytes focuses on such diverse processes as mechanisms of fluid/electrolyte secretion, regulation of cholangiocyte proliferation, roles of cholangiocytes in the pathogenesis of liver fibrosis and … Visa mer In the healthy liver, cholangiocytes contribute to bile secretion via release of bicarbonate and water.
