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 ]
Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase signaling cascade after binding to the proto-oncogenic c-Met receptor. [ 6 ] [ 7 ] Hepatocyte growth factor is secreted by platelets , [ 8 ] and mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial ...
Compensatory liver hyperplasia – The liver undergoes cellular division after acute injury, resulting in new cells that restore liver function back to baseline. Approximately 75% of the liver can be acutely damaged or resected with seemingly full regeneration through hepatocyte division, i.e., hyperplasia. This is what makes living-donor liver ...
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 hepatocytes are on a regular reticulin scaffold and less or equal to three cell thick. The histologic diagnosis of hepatic adenomas can be aided by reticulin staining . In hepatic adenomas, the reticulin scaffold is preserved and hepatocytes do not form layers of four or more hepatocytes, as is seen in hepatocellular carcinoma .
Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
The name is derived from the fact that the cells undergoing this form of cell death increase in size . It is generally considered a form of apoptosis , [ 1 ] and is a descriptor used in the context of inflamed fatty liver ( steatohepatitis ) [ 2 ] (which may be due to obesity or alcohol ), as well as viral hepatitis.
