The typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types. [3]
Liver cytology is the branch of cytology that studies the liver cells and its functions. The liver is a vital organ, in charge of almost all the body’s metabolism. Main liver cells are hepatocytes, Kupffer cells, and hepatic stellate cells; each one with a specific function.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein.
Histopathology of a ballooning hepatocyte.png, H&E stain. Ballooning degeneration centre-left and centre-right. H&E stain. A Councilman body can also be seen in the upper-right of the section. In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death.
The liver is a major metabolic organ exclusively found in vertebrate animals, which performs many essential biological functions such as detoxification of the organism, and the synthesis of various proteins and various other biochemicals necessary for digestion and growth.
Interlobular bile ducts (between the interlobar ducts and the lobules) - simple columnar epithelium. Intralobular bile ducts (cholangioles or Canals of Hering) - simple cuboidal epithelium, then by hepatocytes; Bile canaliculi - two half-canaliculi formed by the hepatocytes facing the perisinusoidal space
Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells , but also acts on haemopoietic progenitor cells and T cells .
Anatomical terms of microanatomy [ edit on Wikidata ] Hepatic stellate cells ( HSC ), also known as perisinusoidal cells or Ito cells (earlier lipocytes or fat-storing cells ), are pericytes found in the perisinusoidal space of the liver , also known as the space of Disse (a small area between the sinusoids and hepatocytes ).
