Fig. 1From: Polygonum multiflorum extract support hair growth by elongating anagen phase and abrogating the effect of androgen in cultured human dermal papilla cellsEffect 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 groupBack to article page
