Abstract
BACKGROUND
Luffa cylindrica stem sap (LuCS) has been ethnopharmacologically used as a cosmetic ingredients to improve the facial condition in Asians, but there is no scientific proof about the advantages of LuCS as a supplement for skin elasticity inducer.
PURPOSE
Presently, we have validated the beneficial effect of LuCS in human preadipocyte and fibroblast.
METHODS
In vitro activities of LuCS on expression of cellular elastin and collagen type I were validated using Western blot analysis in human fibroblasts. Effect of LuCS on preadipocyte development was performed using MDI medium containing isobutyl-methylxanthine, dexamethasone, and insulin and then evaluated using oil red O staining.
RESULTS
Treatment of LuCS stimulated the expression of cellular elastin and type I procollagen in human skin fibroblasts. Exposure to LuCS induced lipid accumulation of preadipocytes via activation of CEBP/α signaling pathway in preadipocytes. Expression of collagen I, elastin, or CEBP/α mRNA was decreased by age. 3-bromo-3-methylisoxazol-5-amine enhanced the synthesis of cellular lipid in preadipocytes.
CONCLUSIONS
Collectively, these results suggest the rationale of LuCS treatment in enhancing the skin condition.
