The migration and proliferation of keratinocytes are key events in re-epithelization, itself a major phase in the wound healing process. Cuscuta japonica Choisy (CJC) is used as a traditional medicine to improve liver, heart, and intestinal function, and its extracts are reported to have various biological properties such as whitening, anti-oxidancy, and an anti-acne effect. However, it is not yet known in particular whether or not CJC essential oil (CJCEO) affects skin regeneration. In the present study, we isolated CJCEO by solvent extraction and tested its effect on wound healing responses using normal human keratinocytes, namely HaCaT cells. We found that CJCEO induced proliferation as well as migration in HaCaT cells in a dose-dependent manner. Compared with a control group, CJCEO treatment at 250 μg/ml increased proliferation by 239.98±5.51% in HaCaT cells in a dose and migration by 124.86±6.06%. Moreover, the oil induced sprout outgrowth and, at 250 μg/ml, increased collagen synthesis by 148.56±15.47% in HaCaT cells. These results demonstrate that CJCEO may promote skin regeneration and wound healing by increasing the migration, proliferation, and collagen synthesis of HaCaT cells. We therefore suggest that CJCEO could be used as a cosmetic material.
