Title: Transcription profiling by array of two different types of human organotypical tissues (bronchial and nasal epithelia) to investigate the effect of repeated whole cigarette smoke (3R4F)      
dateReleased:

description:
The aim of this study was to develop human bronchial and nasal epithelium culture models that are relevant to investigate the impact of cigarette smoke (CS) observed in vivo in respiratory tract tissues in contact with inhaled CS. We used two organotypic cultures generated from primary cells derived from non-smoking donors that contain fibroblasts and epithelial cells in order to reproduce as closely as possible the in vivo situation. To mimic the smoking behavior of a moderate smoker during one day, human tissue cultures (bronchial and nasal epithelium) were exposed repeatedly and directly at the air/liquid interface (using the Vitrocell(R) System) to two doses (high 4.2 ug TPM/cm2 and low 2.2 ug TPM/cm2 per cigarette) of the whole smoke generated by one cigarette or to humidified air (sham). CS exposure was repeated four times with one hour intervals between each cigarette. Various endpoints (e.g., gene and microRNA expression, CYP activity, pro-inflammatory markers release, differential cell counts, cytotoxicity measurement) were then captured to assess the baseline (time 0) and early responses of the tissues after exposure (4 hours) as well as the recovery phase (24 and 48 hours).
