The hepatocyte plates are one cell thick in mammals and two cells thick in the chicken. Sinusoids display a discontinuous, fenestrated endothelial cell lining. The endothelial cells have no basement membrane and are separated from the hepatocytes by the space of Disse, which drains lymph into the portal tract lymphatics. [citation needed]
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] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to the control of the whole metabolism of macromolecules . [ 3 ]
HepaRG cell line is a human hepatic in vitro line used in liver biology research and for assessing liver pathology, hepatotoxicity, and drug-induced injury. The HepaRG model is considered a surrogate for Primary Human Hepatocytes, which are the most pertinent model to reproduce the human liver functioning as they express 99% of the same genes .
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 a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein.
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 ...
Hepatic lipase is expressed mainly in liver cells, known as hepatocytes, and endothelial cells of the liver. The hepatic lipase can either remain attached to the liver or can unbind from the liver endothelial cells and is free to enter the body's circulation system. [ 6 ]
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 ...
The perisinusoidal space also contains hepatic stellate cells (also known as Ito cells or lipocytes), which store vitamin A in characteristic lipid droplets. [ 2 ] This space may be obliterated in liver disease , leading to decreased uptake by hepatocytes of nutrients and wastes such as bilirubin .
