Hepatic stellate cell in the cell body store vitamin A as retinol ester. The function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. When the liver is damaged, stellate cells can change into an "activated" state. The activated stellate cell is characterized by proliferation, contractility, and chemotaxis. This state of the stellate cell is the main source of extracellular matrix production in liver injury. This attribute makes it a key factor in the pathophysiology of the liver. The amount of stored vitamin
Nominalized adjective number and nominative case. "Den Alten" is a similar inflection but in the accusative case. The nominalized adjective is derived from the adjective "alt" and surfaces as it does by taking the appropriate inflection. Like in English, adjectival nouns are used as a plural definite ("the unemployed") and with nationality words ("the Swedish").
