Abstract

Objectives : Atopic dermatitis is an irritable skin disease accompanying rash and itching leading to impaired skin barrier. ATO-ALL is an ethanol extract of natural products comprising 12 herbs and effective on atopic dermatitis. In this study, we aimed to propose that the effect of ATO-ALL on skin regeneration in human keratinocyte cell line, HaCaT cells. Methods : To evaluate the skin regenerating effects of ATO-ALL, scratch wound healing assay, bromodeoxyuridine (BrdU) assay, and propidum iodide (PI) assay were performed using cultured HaCaT cell line. Result : Scratch wound healing assay showed that ATO-ALL was able to enhance the gap filling activity more than 2-fold at 7 ppm concentration compared with control group. BrdU assay demonstrated that ATO-ALL treatment increased the de novo cell proliferation in a dose-dependent manner. Finally, PI assay indicated that the cell cycle of HaCaT cells was modulated by ATO-ALL treatment. Conclusions : These results suggested that ATO-ALL may have skin regenerating effects by increasing cell proliferation via cell cycle regulation. Taken together, ATO-ALL is supposed to have a potential on regeneration of damaged skin or functional disease including atopic dermatitis.
