Hepatic stellate cell fat-staining method to identify the "fat-storing cells" of the liver. 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 of the liver, also known as the space of Disse (a small area between the sinusoids and hepatocytes). The stellate cell is the major cell type involved in liver fibrosis, which is the formation of scar tissue in response to liver damage. Hepatic stellate cells can be selectively stained with gold chloride, but their distinguishing feature in routine histological preparations is the
