Exposition of cigarette smoke to tissue cultures at the air–liquid interface shows in combination of the microarray technology, gene-set analysis and a novel computational modeling an increased secretion of inflammatory mediators, induction of cytochrome P450s activity and overall weak toxicity. The usefulness of in vitro exposure to buccal and gingival organotypic epithelial tissue cultures for the impact assessment of cigarette smoke is demonstrated.
