Aims Recently, immature adipocyte lineage cells have been suggested as a potential hair-growth stimulator. Diverse studies have been attempted to find methods for the preconditioning of immature adipocyte lineage cells. The present study investigates the effect of conditioned medium (CM) from vitamin D3 (Vd3) pre-activated preadipocytes on hair-growth ability. Main methods To test the effect of CM from Vd3 pre-activated preadipocytes on hair-growth efficiency in mice, we compared the differences in hair regenerated after injecting CM from mouse preadipocytes pre-activated with or without Vd3. Next, to determine the regulating factors, the VEGF level was measured by ELISA and angiogenesis level was evaluated by IHC. Finally, the signaling mechanism was investigated by inhibitor kinase assay and western blotting. Key findings The CM from Vd3 pre-activated preadipocyte injection markedly promoted the ability of hair regeneration in mice. The VEGF levels were increased by Vd3 treatment in vitro and the CM from Vd3 pre-activated preadipocytes significantly increased the angiogenesis in vivo, suggesting the involvement of angiognensis in the hair regeneration induced by CM from pre-activated preadipocytes. In signaling study, Vd3-enhanced VEGF production was reduced by an ERK1/2 inhibitor and the level of ERK1/2 phosphorylation was increased by treatment with Vd3. Significance This has been the first report on CM from Vd3 pre-activated preadipocyte displaying stimulatory effects on hair growth via the enhancement of angiogenesis in a hairless-induced C57BL/6 mice.
