The term stellate cells usually refers to neurons in the central nervous system with the shape of star (there are many dendrites raising from the cell body). Stellate nervous cells can be spiny or aspinous. Those cell are located in cerebellum, are inhibitory and GABAergic.
There are also hepatic stellate cells in the perisinusoidal space of the liver involved in the process of fibrosis (response to liver damage).
Another type of stellate cells is found in pancreas-pancreatic stellate cells. These cells look like myofibroblast and are similar to hepatic stellate cells.
