In vitro long-term repeated exposure and exposure switching of a novel tobacco vapor product in a human organotypic culture of bronchial epithelial cells.

ABSTRACT: Next-generation tobacco products and nicotine delivery systems such as heat-not-burn tobacco products and electronic cigarettes, the usage of which is expected to have a beneficial impact on public health, have gained popularity over the past decade. However, the risks associated with the long-term use of such products are still incompletely understood. Although the risks of these products should be clarified through epidemiological studies, such studies are normally performed based on each product category, not product-by-product. Therefore, investigation of the risk on a product-by-product basis is important to provide specific scientific evidence. In the current study, we performed the 40-day repeated exposure of in vitro human bronchial epithelial tissues to cigarette smoke (CS) or vap
