Quantitation of rat hepatic stellate cell contraction: stellate cells’ contribution to sinusoidal resistance

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1999
Although it has been hypothesized that contraction of hepatic stellate cells (HSC) regulates blood flow by modulating sinusoidal resistance, neither HSC contraction nor relaxation has been directly quantitated. To test this hypothesis, a force transducer was employed to directly measure the magnitude and rate of contraction and relaxation by primary ...

Vocal Fold Stellate Cells in the Human Macula Flava and the Diffuse Stellate Cell System

Annals of Otology, Rhinology & Laryngology, 2012
Objectives: Hepatic stellate cells (HSCs) are desmin-positive cells with perinuclear vitamin A droplets that play important roles in liver fibrogenesis. Morphologically similar cells have been found at many extrahepatic sites. Consequently, the concept of a diffuse stellate cell system has been proposed.

Hepatic stellate cells and the reversal of fibrosis

Journal of Gastroenterology and Hepatology, 2006
AbstractHepatic fibrosis is an outcome of many chronic liver diseases, such as viral and autoimmune hepatitis, and of alcohol consumption and biliary obstruction. Prolonged liver injury results in hepatocyte damage, which triggers activation of hepatic stellate cells (HSC) and recruitment of inflammatory cells into the liver.

Hepatic stellate cells

1998
The hepatic stellate cell (HSC) has emerged as a major regulator of normal liver homeostasis and growth, as well as a key effector in the hepatic fibrogenic response. In this chapter, we review the biological characteristics of the hepatic stellate cell, addressing historical perspectives, morphologic characteristics, methods of isolation, and their ...

Hepatic Stellate Cells

2001
Carl Kupffer, by the use of a gold chloride staining method, detected in mammalian livers a population of stellate-shaped cells that were located perisinusoidally, always attached to the sinusoidal capillaries and also to the parenchymal cells (Kupffer 1876, cited by Wake 1980).

Stellate Cells and the Microcirculation

2011
Activation of hepatic stellate cells (HSCs) within hepatic sinusoids during chronic liver diseases is a key feature of the capillarization of sinusoids. This latter feature likely represents an initial cause of portal hypertension during the early development of hepatic fibrosis.
