This study identified a specific subpopulation of hair follicle stem cells in mice and humans that are essential for long-term hair regeneration, highlighting the potential for regenerative therapy.

In this study, local injection of nanosized recombinant human erythropoietin at the injury site improved skin regeneration and re-epithelialization in a mouse model of deep second-degree burns through coexpression of specific receptors.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This chapter reviews the properties and applications of epidermal stem cells in skin tissue engineering and transplantation but reports no new experimental results.

This study demonstrated that intradermal treatment with a medical device using Polynucleotides High Purification Technology (PN HPT) significantly improved skin surface, firmness, pigmentation, and radiance in 30 Asian subjects, with benefits lasting up to six months and no adverse events reported.

This study found that a Wnt/β-catenin signaling activator restored hair regrowth and follicle neogenesis in diabetic mice, suggesting its potential use for treating diabetes-induced hair loss.

This study found that photobiomodulation enhanced hair regeneration in injured dermis of mice, likely through increased migration and exosome secretion of dermal papilla cells via the Akt/GSK-3β/β-catenin pathway.

This review discusses vitamin D and calcium signaling roles in epidermal stem cell processes essential for wound healing but reports no new experimental results, emphasizing their potential interdependent regulatory mechanisms.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.
