Type I cells are the larger of the two cell types; they are thin, flat epithelial lining cells (membranous pneumocytes), that form the structure of the alveoli. They are squamous (giving more surface area to each cell) and have long cytoplasmic extensions that cover more than 95% of the alveolar surface. Type I cells are involved in the process of gas exchange between the alveoli and blood. These cell… WebHuman Pulmonary Alveolar Epithelial Cells (HPAEpiC) may be ordered as frozen ampoules.
