This increased retinyl ester may be due to decreased hepatic uptake of vitamin A and the leaking of esters into the bloodstream from saturated hepatic stellate cells.
12.
The axon dips through the granular layer, into the white matter, before going up to terminate on basket or stellate cells in the molecular layer.
13.
The perisinusoidal space also contains hepatic stellate cells ( also known as cells of Ito ), which store fat or fat soluble vitamins including vitamin A ).
14.
It has a dense network of tangentially oriented fibers and cells made of axons of martinotti cells and stellate cells, as well as apical dendrites of pyramidal cells.
15.
It was at UCSF that Friedman became the first scientist to isolate the hepatic stellate cell, which is responsible for hepatic fibrosis, a scarring process that can lead to cirrhosis of the liver.
16.
Simplified, nerve fibers signals are transported by bushy cells to the binaural areas in the olivary complex, while signal peaks and valleys are noted by stellate cells, and signal timing is extracted by octopus cells.
17.
Soma for these appear in all layers except I . Spiny stellate cells are distinguished from pyramidal cells here by the absence of the apical dendrite and the fact that their axons also do not leave the cortex.
18.
Beginning in 1985 with Friedman's description of the role of the hepatic stellate cell in liver fibrosis, his laboratory at UCSF and then at Mount Sinai has conducted novel studies that have advanced the understanding of liver disease.
19.
GFAP has also been found to be expressed in glomeruli and peritubular fibroblasts taken from rat kidneys Leydig cells of the testis in both hamsters and humans, human keratinocytes, human osteocytes and chondrocytes and stellate cells of the liver in rats.
20.
More recent studies have also shown that in vivo activation of hepatic stellate cells by agents causing liver fibrosis can eventually lead to senescence in these cells, marked by increased SA-beta-galactosidase staining, as well as p53 accumulation and activation of NK cells.
