Cytotoxicity of the ethanol extract of ATRES. Ethanol extracts of ATRES were added to human dermal papilla cells (0–100 ug/mL) and human keratinocyte HaCaT cells (0–5000 ug/mL). The cell viability of the human dermal papilla cells (a) and the human keratinocyte HaCaT cells (b) were measured using an MTT assay for 24 h incubation. The cell viability of HaCaT cells were further determined by adding the ATRES during 72 h incubation (c). Each data value is indicated as the means ± SE for three independent experiments. indicates as compared to the control.
