This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This paper reviews signaling influences and niches of epidermal stem cells and compares various types, but does not present new experimental findings.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This essay discusses the author's views on establishing a successful academic laboratory and reports no new research findings.

In this study, researchers presented a novel therapeutic approach for androgenetic alopecia combining AR-PROTAC degradation with regenerative strategies and evaluated the potential of GT20029 as a topical treatment, proposing a three-phase protocol and future research hypotheses.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.

This study found that hair follicles may provide a safe space for tumor cells in mice, suggesting a potential target for cancer prevention during the dormant phase of tumor development.

This study demonstrates that melanocyte stem cells can be a source of melanoma in a mouse model, resembling human melanoma in both heterogeneity and gene signatures.

This review discusses the interactions and signals affecting skin stem cells and their environments but reports no new experimental results; the authors highlight the need for understanding these processes to enhance tissue rejuvenation and repair.

This audit of ritlecitinib prescribing for severe alopecia areata found that regional practices largely followed national guidelines but highlighted the need for better psychological assessments and more consistent use of SALT scoring to inform treatment continuation decisions after 36 weeks.

This systematic review reports that trichoscopy is highly accurate for diagnosing scalp disorders, suggesting it as a valuable alternative to biopsies and supporting recommendations for its integration into routine dermatology practice.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.

This study demonstrates that hair follicle bulge stem cells can transition into other stem cell compartments, indicating their role in maintaining both hair follicles and sebaceous glands.

Hair follicle stem cells rely on nearby blood vessels for their maintenance and function.

This review discusses lung regeneration and highlights the role of facultative stem/progenitor cells, but it reports no new findings and calls for further exploration of underlying mechanisms.

This review discusses advancements in understanding the biology and pathology of the epidermis and hair follicles, reporting no new clinical results but highlighting the synergy between research and dermatologic patient care.

This study found that a specific Gli1+ subpopulation in the perivascular niche plays a crucial role in wound healing by differentiating into myofibroblasts, with their genetic ablation impairing wound repair.

This study observed significant differences in the skin microbiome between hidradenitis suppurativa patients and healthy individuals, notably with decreased β-diversity and a distinct abundance of certain bacteria in affected skin.

This article from the 4th Intercontinental Meeting of Hair Research Societies provides no abstract or new findings.

This study reported that in degenerative alopecia, Zn²⁺/Cu²⁺-dependent proteases are downregulated and destabilized, and a specially developed microneedle patch reactivated these enzymes, reduced senescence, and enhanced hair regeneration in an animal model.

Mesenchymal stiffness affects sweat gland cell development.

This study highlights exosome-based therapies as promising treatments for androgenetic alopecia, detailing protocol development, quality control measures, and clinical application examples, with mesenchymal stem cell-derived exosomes improving hair density in a case study without adverse effects.

In this study, aged mice showed better regenerative skin outcomes than young mice, linked to a specific fibroblast subpopulation and enhanced signaling interactions that promote regeneration. EREG treatment improved young mice's skin regeneration, suggesting potential for scarless therapies.

This study explores how chromatin differences between dermal papilla cells and papillary fibroblasts contribute to hair follicle inductivity and investigates the regulatory changes in androgenic alopecia.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.
