Hepatic stellate cell
Hepatic stellate cells (here HSC), also known as perisinusoidal cells or Ito cells (earlier ''lipocytes'' or ''fat-storing cells''), are pericytes found in the perisinusoidal space (a small area between the sinusoids and hepatocytes) of the liver also known as the space of Disse. The stellate cell is the major cell type involved in liver fibrosis, which is the formation of scar tissue in response to liver damage.
==Staining==
Hepatic stellate cells can be selectively stained with gold chloride, but their distinguishing feature in routine histological preparations is the presence of multiple lipid droplets in their cytoplasm. Cytoglobin expression has been shown to be a specific marker with which hepatic stellate cells can be distinguished from portal myofibroblasts in the damaged human liver. In murine liver, Reelin expressed by Ito cells has been shown to be a reliable marker in discerning them from other myofibroblasts. The expression of reelin is increased after liver injury.
