Inflammatory and Oxidative Stress Responses of an Alveolar Epithelial Cell Line to Airborne Zinc Oxide Nanoparticles at the Air-Liquid Interface: A Comparison with Conventional, Submerged Cell-Culture Conditions
Figure 1
Schematic of the two cell exposure models used for studying particle-cell interaction. (a) Exposure at the air-liquid interface (ALI): airborne particles are directly deposited on cells grown at the air-liquid interface. (b) Exposure under submerged conditions: particles were suspended directly in the cell culture medium covering the cells.
