The goal of this CTP supplement to a parent grant (which funds the study of alveolar epithelial type 2 cells [AEC2s], a type of lung cell) is to determine the effects of e-cigarette vapor exposure on the human alveolar epithelium (the internal surface area of the lung). Researchers will use newly-developed protocols to generate human AEC2s from induced pluripotent stem cells (iPSCs). They will culture the AEC2s using an air-liquid interface method and then expose them to (1) e-cigarette vapor containing nicotine, (2) e-cigarette vapor containing vitamin E-acetate (implicated in e-cigarette/vaping acute lung injury, or EVALI), (3) cigarette smoke, or (4) air (a control condition). Researchers will then measure the effects of these exposures on the RNA molecules, proteins, and metabolites in the AEC2s and generate a dataset. Study findings will describe e-cigarette vapor injury to this key lung cell type.
