Description
Type I alveolar epithelial cells are large squamous cells, which extend across several air sacs and cover more than 95% of the alveolar surface area. They are specialized to serve as very thin (often only 25 nm in width) gas-permeable components of the blood-air barrier. The Type I Alveolar cells are the target of many insults, including ventilator-induced lung injury. These cells are useful in investigating the function and pathology of the respiratory system
