The key idea here is which cells are conventionally taught as the three main liver cell types in basic histology. The liver’s functional parenchymal cells are hepatocytes, which carry out most metabolic tasks and make bile. Among nonparenchymal cells, Kupffer cells sit in the sinusoids as resident macrophages, and biliary epithelial cells (cholangiocytes) line the bile ducts and form the biliary tree. These three are typically highlighted as the primary cell types you should recognize.

Hepatic stellate cells, also known as Ito cells, reside in the space of Disse between hepatocytes and sinusoidal endothelium. They store vitamin A in their lipid droplets and, when activated in liver injury, become fibrogenic and produce extracellular matrix, contributing to fibrosis. While they play a crucial role in liver pathology and physiology, they are not usually listed among the three main liver cell types in introductory discussions.

So, hepatic stellate cells are not considered one of the three main liver cell types.
