This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.

This review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This study observed that Aconiti Ciliare Tuber extract may promote hair growth in mice by activating the Wnt/β-catenin signaling pathway.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.
