A Primer on Pulmonary Cell Biology: Lung Cells and their Functions
The lung contains over 40 different cell types. Each has a variety of structural and metabolic functions that may be altered by disease states. The potential funetions of some of these cells have been studied in detail (1,2), while the activities of other cell types are little known. In this diseussi on we will emphasize several specifie cells that are important in a variety of syndromes of lung injury. For practical purposes the cells of the pulmonary parenehyma ean be divided into a few groups.
