A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. These cells are involved in: Protein synthesis; Protein storage; Transformation of carbohydrates; Synthesis of cholesterol, bile salts and phospholipids; Detoxification, modification, and excretion of exogenous and endogenous substances
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 .
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 ]

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.
Apoptosis of the liver of a mouse. Hepatocytes are the liver's primary parenchymal cells, forming 80% of the liver's mass and 60% of its cells. They are round in shape and contain a nucleus and organelles that contribute to metabolic and secretory functions. [5] Hepatocytes also play a pivotal role in liver inflammation. [6]
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 function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. [7] When the liver is damaged, stellate cells can change into an activated state.
