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:
Liver cytology is the branch of cytology that studies the liver cells and its functions. The liver is a vital organ, in charge of almost all the body’s metabolism. Main liver cells are hepatocytes, Kupffer cells, and hepatic stellate cells; each one with a specific function.
Hepatic stellate cells (HSC), also known as perisinusoidal cells or Ito cells (earlier lipocytes or fat-storing cells), are pericytes found in the perisinusoidal space of the liver, also known as the space of Disse (a small area between the sinusoids and hepatocytes).
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.
[2] [3] [4] In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm and mostly shielded by the lower right rib cage. Its other metabolic roles include carbohydrate metabolism , the production of hormones , conversion and storage of nutrients such as glucose and glycogen , and the decomposition of red blood cells .
A liver support system or diachysis is a type of therapeutic device to assist in performing the functions of the liver. Such systems focus either on removing the accumulating toxins (liver dialysis), or providing additional replacement of the metabolic functions of the liver through the inclusion of hepatocytes to the device (bioartificial liver device).
Six small non-avian dinosaur eggs, no bigger than grapes, were discovered during a field study in Ganzhou, China, in 2021. These eggs now mark the smallest-ever found in the world.
(Lipopolysaccharide (LPS) is a bacterial endotoxin which is found in the cell wall gram-negative bacteria, whereas lipoteichoic acid is present in gram-positive bacteria.) Because of this detection system, Kupffer cells play a critical role in initiating and mediating immune responses to bacterial infection of the liver.
