The air-liquid interface and use of primary cell cultures are important to recapitulate the transcriptional profile of in vivo airway epithelia.

ABSTRACT: Organotypic cultures of primary human airway epithelial cells have been used to investigate the morphology, ion and fluid transport, innate immunity, transcytosis, infection, inflammation, signaling, cilia, and repair functions of this complex tissue. However, we do not know how closely these cultures resemble the airway surface epithelium in vivo. In this study, we examined the genome-wide expression profile of tracheal and bronchial human airway epithelia in vivo and compared it with the expression profile of primary cultures of human airway epithelia grown at the air-liquid interface. For comparison, we also investigated the expression profile of Calu-3 cells grown at the air-liquid interface and primary cultures of human airway epithelia submerged in nutrient media. We found that the transcriptional profile of differentiated primary cultures grown at the air-liquid interface most closely resembles that of in vivo airway epithelia, suggesting that the use of primary cultures and the presence of an air-liquid interface are important to recapitulate airway epithelia biology. We describe a high level of similarity between cells of tracheal and bronchial origin within and between different human donors, which suggests a very robust expression profile that is specific to airway cells.

Project description:Inhalation is the most relevant entry point for nanoparticles (NPs) into the human body. To date, toxicity testing of nanomaterials in respect to oral, dermal and inhalative application is mainly based on animal experiments. The development of alternative test methods is the subject of current research. In vitro models can help to investigate mechanistic aspects, as e.g. cellular uptake or genotoxicity and might help to reduce in vivo testing. Lung cell lines are proper in vitro tools to assess NP toxicity. In respect to this, various cell models have been developed during the recent years, but often lack in a proper intact barrier function. However, besides other important in vivo criteria which are still missing like e.g. circulation, this is one basic prerequisite to come closer to the in vivo situation in certain mechanistic aspects such as particle translocation which is an important task for risk assessment of nanomaterials. Novel developed in vitro models may help to investigate the translocation of nanomaterials from the lung. We investigated the barrier function of the recently developed human lung cell lines CI-hAELVi and CI-huAEC. The cells were further exposed to CeO2 NPs and ZnO NPs, and their suitability as in vitro models for toxicological investigations was proven. The obtained data were compared with data generated with the A549 cell line. Measurement of transepithelial resistance and immunohistochemical examination of tight junctions confirmed the formation of a functional barrier for both cell lines for submerged and air-liquid cultivation. For particle exposure, hAELVi and huAEC cells showed comparable results to A549 cells without losing the barrier function. CeO2 NP exposure revealed no toxicity for all cell lines. In contrast, ZnO NPs was toxic for all cell lines at a concentration between 10-50 ?g ml-1. Due to the comparable results to A549 cells CI-hAELVi and CI-huAEC offer new opportunities to investigate nanoparticle cell interactions more realistic than recent 2D cell models.
