Effects of particulate matter and resveratrol on human keratinocyte viability. Viability of keratinocytes treated with (A) PM10 (0, 1.25 μg/mL, 3 μg/mL, 6 μg/mL, 12 μg/mL, 25 μg/mL, 50 μg/mL, 100 μg/mL, or 200 μg/cm2) or (B) resveratrol (0, 0.01 μg/mL, 0.1 μg/mL, 1 μg/mL, 10 μg/mL, 50 μg/mL, or 100 μM) for 24h measured using the water-soluble tetrazolium salt assay. Data are presented as the mean ± standard deviation of three independent experiments (n = 3). The ratio of surviving cells is relative to the untreated control. PM, particulate matter.
