The liver is responsible for storing approximately 80% of the body's total vitamin A, with the bulk of this crucial nutrient concentrated within hepatic stellate cells. Understanding what are hepatic stellate cells vitamin A reveals their pivotal and dual role in maintaining liver homeostasis and contributing to disease pathogenesis.

The liver is the body's primary storage site for vitamin A, with approximately 80% of the body's total supply stored within it. The specialized cells responsible for this vital function are known as hepatic stellate cells, or Ito cells. These quiescent, star-shaped cells sequester vitamin A within cytoplasmic lipid droplets, playing a critical role in maintaining systemic vitamin A homeostasis.
