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 typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types. [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.
The Kupffer cells of liver are phagocytic cells that help in the phagocytosis of dead blood cells and bacteria from the blood. [ 57 ] The liver is responsible for immunological effects – the mononuclear phagocyte system of the liver contains many immunologically active cells, acting as a 'sieve' for antigens carried to it via the portal system .
When the chylomicron remnants become small enough (30–80 nm), they pass through the LSEC fenestrations, leading to their metabolism in hepatocytes. Reduced porosity, as in liver cirrhosis , diabetes mellitus or old age may lead to prolonged postprandial lipoproteinemia and increased circulatory cholesterol levels, with increased risk for ...
Phagocytic cells (of the mononuclear phagocyte system) called macrophages engulf (phagocytose) the hemoglobin to degrade it, producing hemosiderin and biliverdin. Excessive systemic accumulations of hemosiderin may occur in macrophages in the liver, lungs, spleen, kidneys, lymph nodes, and bone marrow.
Kupffer cells are integral in the innate responses of the immune system. They are important for host defense and play a role in the metabolism of many different compounds including, lipids, protein complexes and small particles. They are also useful in removing apoptotic cells from circulation. [2] [3]
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 ...
