Piecemeal necrosis in liver aka interface hepatitis is necrosis of the limiting plates, by inflammatory cells. It may be identified as actual necrosis of cells or by irregularity of the limiting plates which is caused IOS's hepatocytes and replacement with inflammatory cells and/or fibrosis.
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]
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
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.
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.
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.
In histo pathology, feathery degeneration, formally feathery degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death associated with cholestasis. [ 1 ] Cells undergoing this form of cell death have a flocculant appearing cytoplasm, [ 2 ] and are larger than normal hepatocytes.
The perisinusoidal space (or space of Disse) is a space between a hepatocyte, and a sinusoid in the liver.It contains the blood plasma. Microvilli of hepatocytes extend into this space, allowing proteins and other plasma components from the sinusoids to be absorbed by the hepatocytes.
