Abstract

Background: Hair color retention and rejuvenation have recently emerged as a new research hot spot, with many studies focused on developing treatments to prevent premature greying.Aim: This study is aimed to explore the hair-blacking effects and possible mechanisms of Cerasus serrulata flower extracts (CSE) using a C57BL/6 premature greying mouse model.Materials and Methods: The variations in hair follicle number, hair follicle depth and cortical thickness were evaluated by hematoxylin and eosin staining. The quantity changes of melanocytes were also evaluated using Masson-Fontana Melanin staining. The relative abundance of vascular endothelial growth factor (VEGF), β-catenin and tyrosinase transcripts following transformed growth were further quantified using RT-qPCR and immunofluorescence. The changes in protein level expression of β-catenin, VEGF and tyrosinase were also evaluated by western blot.Results: The β-catenin and VEGF expression were significantly up-regulated in skin tissues treated with C. serrulata extracts, promoting hair growth and blackening.Conclusion: CSE can promote the efficient hair-blacking likely via the VEGF pathway, making it a potential therapeutic candidate for treating premature greying.

Keywords: Cerasus serrulata flower extracts (CSE); Hair-blackening; β-Catenin; VEGF; Tyrosinase
