Organotypic human nasal epithelium culture 4 hours after exposure to diluted mainstream cigarette smoke (0.15 mg nicotine/l) from 3R4F reference cigarettes. Organotypic nasal MucilAirTM cultures were consisted of nasal epithelial cells derived from a healthy non-smoker 41-year old female, fully differentiated and cultured at the air-liquid interface (37°C, 5% CO2, 90% humidity) and maintained in the respective culture medium in 12-well culture plates (0.7 ml/well), with a medium change every 2 – 3 days, for a maximum of 12 days before exposure. After exposure, the medium was not changed until it was collected.

Each 3R4F cigarette was smoked to a defined standard butt length (approximately 35 mm), yielding approximately 10 – 11 puffs per stick. The cultures were exposed to smoke continuously for 28 minutes in smoking machine and 4 hours after smoke exposure the cells were collected for RNA extraction.
