ROS generation in human nasal fibroblasts treated with UPM as measured by flow cytometry. a Dose-dependent ROS generation in human nasal fibroblasts exposed to UPM. b Time-dependent ROS generation in human nasal fibroblasts exposed to UPM. ROS were quantified by flow cytometry with DCF-DA. Data are presented as the mean ± SEM. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. the control group. ROS: reactive oxygen species; UPM: urban particulate matter; DCF-DA: 2′,7′-dichlorofluorescin diacetate; SEM: standard error of the mean
