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]
Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells , but also acts on haemopoietic progenitor cells and T cells .
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
The human liver is particularly known for its ability to regenerate, and is capable of doing so from only one quarter of its tissue, [35] due chiefly to the unipotency of hepatocytes. [36] Resection of liver can induce the proliferation of the remaining hepatocytes until the lost mass is restored, where the intensity of the liver's response is ...
The tumor is an adenocarcinoma derived from a primary lesion in the body of the pancreas. Main article: Liver cancer Most cases are metastases from other tumors , frequently of the GI tract (like colon cancer , carcinoid tumors mainly of the appendix , etc .), but also from breast cancer , ovarian cancer , lung cancer , renal cancer , prostate ...
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]
Oxidative DNA damage is mutagenic [27] and also causes epigenetic alterations at the sites of DNA repair. [28] Epigenetic alterations and mutations affect the cellular machinery that may cause the cell to replicate at a higher rate or result in the cell avoiding apoptosis, and thus contribute to liver disease. [29]
The complications are hepatic encephalopathy and impaired protein synthesis (as measured by the levels of serum albumin and the prothrombin time in the blood). The 1993 classification defines hyperacute as within 1 week, acute as 8–28 days, and subacute as 4–12 weeks; [ 1 ] both the speed with which the disease develops and the underlying ...
