Hepatocyte nuclei are round with dispersed chromatin and prominent nucleoli. Anisokaryosis (or variation in the size of the nuclei) is common and often reflects tetraploidy and other degrees of polyploidy, a normal feature of 30-40% of hepatocytes in the adult human liver. [4] Binucleate cells are also common. [citation needed]
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.
Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2]
Each lobule is made up of millions of hepatic cells (hepatocytes), which are the basic metabolic cells. The lobules are held together by a fine, dense, irregular, fibroelastic connective tissue layer extending from the fibrous capsule covering the entire liver known as Glisson's capsule after British doctor Francis Glisson .

The Kupffer cells can take up and destroy foreign material such as bacteria. Hepatocytes are separated from the sinusoids by the space of Disse. Hepatic stellate cells are present in the space of Disse and are involved in scar formation in response to liver damage. Defenestration happens when LSECs are lost rendering the sinusoid as an ordinary ...
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). The stellate cell is the major cell type involved in liver fibrosis, which is ...
Hepatocytes are polyhedral in shape, therefore having no set shape or design, although they are made of cuboidal epithelial cells. They have surfaces facing the sinusoids (called sinusoidal faces) and surfaces which contact other hepatocytes (called lateral faces). Bile canaliculi are formed by grooves on some of the lateral faces of these ...
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; Abdominal ultrasonography (with Doppler) of dilated intrahepatic bile ducts, in this case because of pancreatic cancer. The bile ducts are ...
