A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. Hepatocytes make up 80% of the liver's mass. These cells are involved in:
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 ]
The gene coding for human SAA1 is one of the 4 SAA genes mapped to a region in the short arm on Chromosome 11. [12] Two of these genes, SAA1 and SAA2, are inducible during acute-phase response, whereas SAA3 is a pseudogene in humans [13] and SAA4 is constitutively expressed in a variety of tissues and cells. Single nucleotide polymorphisms ...
HNF-4α is a nuclear transcription factor that binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor that regulates the expression of several hepatic genes. This gene plays a role in development of the liver, kidney, and intestines. Alternative ...
Undifferentiated hepatocyte-like cells appear in small, individualized, colonies The cells are available as undifferentiated growth-stage cells that can be grown in-house with the possibility of cell manipulation and amplification; or as fully differentiated cells that are ready and easy-to-use cells with high inter-assay reproducibility and ...
That is, the hepatocytes go from the quiescent G0 phase to the G1 phase and undergo mitosis. This process is activated by the p75 receptors. [79] There is also some evidence of bipotential stem cells, called hepatic oval cells or ovalocytes (not to be confused with oval red blood cells of ovalocytosis), which are thought to reside in the canals ...
Forkhead box protein A2 (FOXA2), also known as hepatocyte nuclear factor 3-beta (HNF-3B), is a transcription factor that plays an important role during development, in mature tissues and, when dysregulated or mutated, also in cancer.
Phagocytes are usually not bound to any particular organ but move through the body interacting with the other phagocytic and non-phagocytic cells of the immune system. They can communicate with other cells by producing chemicals called cytokines , which recruit other phagocytes to the site of infections or stimulate dormant lymphocytes . [ 53 ]
