Abstract

|
|
Objectives : Currently, the alopecia is one of the most emotionally stressful syndromes in human life. Human hair dermal papilla cells (HDPCs) play an essential role in controlling hair growth and in regulating hair cycle. We performed MTT assay, cell cycle, and western blot to determine the effects of essential oil from Coicis Semen (ECS) on hair growth in HDPCs.
Methods : We monitored cell proliferations by MTT assay in HDPCs. After setting up the safe and effective concentration range to be treated ECS, cell cycle analysis was performed using flow cytometry. Also, the protein expression of hair growth-related factors such as insulin like growth factor-1 (IGF-1), Wnt, extracellular signalregulated kinase (ERK), serine/threonine-specific protein kinase (Akt) in HDPCs was determined by western blot.
Results : As results, cell proliferation was increased in ECS group compared to dimethyl sulfoxide (DMSO) group and minoxidil (MNXD) group. Cell number of ECS group was more decrease in sub G1 phase than cell number of DMSO group. Also, cell number of ECS group increased compared to cell number of DMSO group in G1 phase. Protein expression of ECS group was higher than protein expression of DMSO group on related hair growth factors (IGF-1, Wnt, ERK, Akt).
Conclusion : As mentioned above, ECS increased cell proliferation and the protein expression of IGF-1, Wnt, ERK, and Akt. These results suggest that ECS could be used as a potential material for the treatment of alopecia by increasing the proliferation of HDPCs.
