Barrier dysfunction caused by counterfeit vape cartridges in bronchial epithelial cells. 16-HBE cells were cultured on transwell inserts and exposed to 2 puffs of 70 mL of air, MCT, vitamin E acetate (50% w/v), and counterfeit vape cartridge for 10 min. Twenty-four hours later, the resistance was measured by an EVOM2 device. One-way ANOVA ** p < 0.01 vs. air (n = 3).
