This abstract provides guidance on where to find authors' assigned levels of evidence for articles in the journal, but it does not report any research findings from a specific study.

This study concluded that controlled micro-injury induces hair regeneration and vitiligo repigmentation in mice, potentially through the Wnt/β-catenin pathway.

This research describes methods to activate melanocyte stem cells during hair follicle regeneration and to isolate melanocytes from neonatal mouse skin, with the aim of studying melanogenesis for potential clinical applications.

In this study of four Chinese goat breeds, black goats exhibited significantly higher melanin content, while Inner Mongolian cashmere goats had longer fiber lengths. These findings highlight genetic variations in coat color and fiber length, informing future breeding programs.

In this murine study, researchers found that topical treatment with Philippine stingless bee propolis increased folliculogenesis, epidermal thickness, and melanogenesis, but not hair length, potentially supporting hair follicle regeneration and melanocyte function in chemotherapy-induced alopecia models.

This study found that non-vitiliginous melanocyte stem cells from vitiligo patients were unaffected by the disease and could effectively differentiate into melanin-producing melanocytes, suggesting their potential for use in cellular therapy for vitiligo repigmentation.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

This review discusses the role of epidermal and other adult stem cells in skin repair, focusing on their potential therapeutic applications for non-healing wounds and other skin disorders, but reports no new research results.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.

This review discusses the potential role of vitamins and minerals in managing non-scarring alopecia but reports no clinical results; the authors advocate for further controlled trials to explore these relationships.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This review discusses melanocyte biology and its genetic and molecular basis, highlighting its relevance in understanding diseases like vitiligo and albinism, and reports no new findings.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

In this study, researchers found that electrospun membranes with aligned surface topography advanced the immune response towards an adaptive stage and highlighted the role of T cells in hair follicle regeneration in mice, showcasing the intricate interactions between immune and skin cells.
