Effect of PM extract on DPCs’ viability and mitochondrial activity. DPCs were treated with 10 μg/ml and 100 μg/ml of PM extract for 24 h. a Cell viability of DPCs treated with PM extract was measured using CCK8 assay. b JC-1 aggregates (A590)/monomer (A530) ratio of DPCs treated with PM extract. c Distribution of JC-1 aggregates (590 nm, red) and monomer (530 nm, green) by immunofluorescence photography. Data are presented as mean ± SD. n > 3 for each group. *p < 0.05, **p < 0.01 compared with control group
