Ascorbigen (ABG) is the predominant indole-derived compound from Brassica vegetables. In this study, we attempted to evaluate the effects of ABG on hair growth. To this end, we examined the proliferation of isolated human dermal papilla (DP) cells and keratinocytes after incubation in various concentrations (0-1.25mM) of ABG. Furthermore, hair shaft regrowth was monitored in a mouse model of chemotherapy-induced alopecia (CIA), and hematoxylin and eosin staining was performed for histological analyses. We found that 1.25mM ABG induced a 1.2-fold increase in the growth of DP cells, but not keratinocytes. However, ABG did not exert significant protective effects against CIA in the mouse model. These findings suggest that ABG may not be able to counteract CIA and that further investigation of the therapeutic potential of ABG in disease models is required.
