Function of stellate cells
WebStellate cells, either hepatic (HSCs) or pancreatic (PSCs), are a type of interstitial cells characterized by their ability to store retinoids in lipid vesicles. In pathological conditions both HSCs and PSCs lose their retinoid content and transform into fibroblast-like cells, contributing to the fibrogenic response. HSCs also participate in other functions …

WebIto cells (perisinusoidal fat-storing cells, stellate cells, lipocytes) of the liver are mesenchymal cells located in the space of Disse. They are the main place of vitamin A storage in characteristic lipid droplets. Moreover, they demonstrate synthetic activity of collagens and other extracellular matrix proteins involved in hepatic fibrosis. WebThis work highlights the unique transcriptional niche of stellate cells, and identifies potential stellate cell targets for tracking, targeting and isolation. Hepatic stellate cell signature expression may identify patients with HCV cirrhosis …
WebThe hepatic stellate (Ito) cell lies within the space of Disse and has a variety of functions. Stellate cells store vitamin A in characteristic lipid droplets. In the normal human … WebIn physiological conditions, LSECs regulate hepatic vascular tone contributing to the maintenance of a low portal pressure despite the major changes in hepatic blood flow occurring during digestion. LSECs maintain hepatic stellate cell quiescence, thus inhibiting intrahepatic vasoconstriction and fibrosis development.

Although, the study of stellate cell behavior has been gained through animal models and primary HSCs isolation, which undergo spontaneous activation that correlates closely with their response in vivo .
WebT Stellate cells are sharply tuned; as a population they encode the spectrum of sounds. In these neurons, phasic excitation from the auditory nerve is made more tonic by feedforward excitation, coactivation of inhibitory with excitatory inputs, relatively large excitatory currents through NMDA receptors, and relatively little synaptic depression.
WebSep 5, 2024 · Kupffer cells (also known as stellate sinusoidal macrophages or Kupffer-Browicz cells) are macrophages found in the sinusoids of the liver. Kupffer cells make up 80% to 90% of all the macrophages in the entire human body.[1] They are a component of the host immune system and are involved in the metabolism of various compounds. … has speaker of the house been decided yetStellate cells are neurons in the central nervous system, named for their star-like shape formed by dendritic processes radiating from the cell body. Many stellate cells are GABAergic and are located in the molecular layer of the cerebellum.

Quiescent stellate cells represent 5-8% of the total number of liver cells. Each cell has several long protrusions that extend from the cell body and wrap around the sinusoids. The lipid droplets in the cell body store vitamin A as retinol ester. The function and role of quiescent hepatic stellate cells is unclear.
