In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This study suggests that exosomes from dermal papilla cells can regulate hair follicle stem cell proliferation via the Wnt3a/β-catenin signaling pathway, potentially informing treatment for human hair problems.

This study found that dermal papilla cell-derived exosomes promote hair follicle regeneration during wound healing by enhancing fibroblast activity and activating the Wnt/β-catenin signaling pathway in mice.

In this study, researchers identified exosomal miR-199a-3p as a key factor in the regulation of melanogenesis by dermal papilla cells, finding that it enhances melanocyte proliferation and melanin production, suggesting potential therapeutic targets for pigmentation disorders.
