Description：Human Pulmonary alveolar epithelial cells (HPAEpiC,人肺泡上皮細(xì)胞), also called Human Pneumocytes, are separated from human lung tissue. Human lung alveolar epithelial cells line the alveoli and comprise of 2 subtypes of epithelial cells known as Type I Alveolar Cells (AT1) and Type II Alveolar Cells (AT2).

Type 1 vs Type 2 Pneumocytes

AT1 cells are large squamous cells that account for over 95% of the alveolar surface area, type II cells are much smaller than Type I, scattered between Type I and adjacent alveolar septal junctions. Type I pneumocytes form the epithelial component of the thin air–blood barrier, while Type II pneumocytes secrete surfactants that form a fatty film to lowering surface tension. AT2 cells can also differentiate to replace damaged AT1 cells. Type II Alveolar cells contain Na+-, K+-ATPase and amiloride-sensitive epithelial Na+ channels.；
