Effect of RGE on HHDPC proliferation and apoptosis. HHDPCs were treated with various concentrations of RGE or MNX (100 μM) for 24 h. (A) Cell viability was measured using MTT assays, added as a percentage of the vehicle-treated control. (B) Cells were treated with RGE (100 μg/mL) or MNX (100 μM) for 24 h and protein expressions of Bcl-2 and Bax were analyzed by Western blotting. Data show the mean±SD of at least three independent experiments. *P<0.05 values are considered significantly different. HHDPC, human hair dermal papilla cells; MNX, minoxidil; MTT, 3-[4,5-dimeth-ylthiazol-2-yl]-2,5-diphenyltetrazolium bromide; RGE, red ginseng extract.
