Fig. 1. Rg4 increases cell viability in 3D-cultured HDP cells. (A) Chemical structure of ginsenoside Rg4. (B, C) Twoand three-dimensional cultured dermal papilla cells were treated with Rg4 (5-100 μg/ml) for 48 hours. Viability of DP cells were carried out by WST-1 assay. (D) Images showed DP sphere size which treated with Rg4 (5-200 μg/ml) for 48 hours. (E, F) The diameter and area of the DP spheres size was showed by graph through captured image. The results were presented as the mean ± SD of three independent experiments. *p < 0.05 versus DMSO-treated control. Scale bars: C, 200 μm.
