The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This study found that hair follicle stem cells can effectively enhance nerve regeneration and restore function in peripheral nerve injuries in mice, suggesting their potential as a source for autologous stem cell therapy.

In this study, hair follicle stem cells from ND-GFP transgenic mice were observed to be pluripotent, effectively repairing peripheral nerve and spinal cord injuries in mouse models.

This article reviews mammalian skin epidermis as a model for studying stem cell regulation, noting the utility of in vitro and ex vivo platforms, but it reports no new empirical findings.

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.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

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 study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This study examines the role of hair follicle stem cells in epidermal regeneration during skin soft tissue expansion, proposing a potential method for their cellular and molecular regulation.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

This review discusses melanocyte stem cells in hair follicles and their potential role in cell-based therapy for vitiligo, reporting no new experimental results.

This review highlights advances in understanding inflammatory memory in epidermal stem cells, focusing on their capacity to remember prior inflammatory responses and respond more quickly to future stimuli, potentially aiding strategies against skin-related diseases.

This article reviews recent research on adult epidermal stem cells, discussing their properties and potential for reprogramming into patient-specific therapies, and emphasizes the need for further development while minimizing cancer risk.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

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.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This review examines the complex mechanisms that regulate skin stem cell development, activation, and differentiation, emphasizing the molecular signaling pathways that influence their fate and contribute to skin homeostasis.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study developed an efficient method for isolating and enriching multipotent ovine hair follicle stem cells, which may aid in research on the ovine hair cycle and future wool production.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

ABS-201 may effectively promote hair growth in men by targeting the prolactin receptor.

This study found that androgenetic alopecia may involve a defect in the conversion of hair follicle stem cells to progenitor cells, as demonstrated by a reduced presence of progenitor cells in bald scalp samples.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.
