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]
Hepatocytes constitute about 80% of the cell population of the liver, with the other 20% being occupied by Kupffer cells, hepatic stellate cells, endothelial cells and mesothelial cells, which are not exactly characteristic of the liver, but are present in the liver samples. [2] Histologically speaking, hepatocytes have specific characteristics.
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.
Micrograph showing ground glass hepatocytes. H&E stain. In liver pathology, a ground glass hepatocyte, abbreviated GGH, is a liver parenchymal cell with a flat hazy and uniformly dull appearing cytoplasm on light microscopy. The cytoplasm's granular homogeneous eosinophilic staining is caused by the presence of HBsAg.
Cytoglobin expression has been shown to be a specific marker with which hepatic stellate cells can be distinguished from portal myofibroblasts in the damaged human liver. [2] In murine (rats, mice) liver, reelin expressed by Ito cells has been shown to be a reliable marker in discerning them from other myofibroblasts . [ 3 ]
Jaundice (yellow skin and/or whites of the eyes) This is where bilirubin deposits in skin, causing an intense itch. Itching is the most common complaint by people who have liver failure. Often this itch cannot be relieved by drugs. Swelling of the abdomen, and swelling of the ankles and feet occurs because the liver fails to make albumin.
Of the four recluse spiders in the United States that are venomous, all of them produce cytotoxins, which cause tissue death.Along with infection, tissue death resulting in necrosis is the biggest ...
The virus is one of the smallest enveloped animal viruses. The 42 nm virions, which are capable of infecting liver cells known as hepatocytes, are referred to as "Dane particles". [41] In addition to the Dane particles, filamentous and spherical bodies lacking a core can be found in the serum of infected individuals. [42]
