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
Spermaceti organ Spermaceti organ The spermaceti organ is an organ that commonly appears in the heads of toothed whales of the family Physeteroidea, in particular the sperm whale. This organ contains a waxy liquid called spermaceti and is involved in the generation of sound. In the modern day Great Sperm Whale ("Physeter macrocephalus"), the spermaceti organ is far larger in proportion to the animal’s body than what would be explained by simple allometry, and the evolution of the organ has caused changes in basal skull morphology, which may implicate tradeoffs were made that compromised the functionality of other nearby features.
