HaCaT keratinocytes were treated with fisetin (0–10 μM) for 2 h prior to exposure to 100 μg/mL PM2.5 for 24 h. The cells were subsequently harvested and stained with a Muse Caspase-3/7 Assay Kit (Luminex), following which the cells were incubated with 7-aminoactinomycin D (7-AAD) for detecting the apoptotic cells. The population of caspase-3/7+ apoptotic cells was measured using a Muse Cell Analyzer.
