This article outlines the rationale, design, major findings, and updated objectives of the ongoing Rotterdam Study, without presenting new research data.

This study found that patterned hair plucking in mice triggers a collective regeneration response in nearby unplucked hair follicles via a quorum sensing mechanism involving immune signaling.

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 study identified genetic variants in the Trichohyalin gene that account for approximately 6% of the variance in hair morphology among Australians of European descent.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

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 review discusses the role of stem cells in cutaneous wound healing and reports no clinical results; the authors highlight the need for better understanding of underlying mechanisms for future therapies.

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

This study found that sebaceous-gland-derived glycerol significantly contributes to stratum corneum hydration in mice with sebaceous gland deficiencies.

This review discusses the potential of electrospun gelatin-based nanofiber dressings for wound healing and skin regeneration, detailing their properties, enhanced functionalities through crosslinking and bioactive components, and their application in treating challenging wound types like burns and diabetic wounds.

This study found that dutasteride increased scalp hair growth in men with male pattern hair loss, particularly at a 2.5 mg dose, and was more effective than finasteride over 24 weeks.

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

This review examines current treatments and the potential role of stem cells in cutaneous wound healing, but it presents no new clinical results and calls for more research on mechanisms.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This study reports a novel LC/MS method that separates and analyzes all known ceramide subclasses in human stratum corneum, identifying a new subclass, CER [EOdS], with minimal sample preparation.

This review discusses the niches supporting adult stem cells in various organisms, including well-studied germline niches and the less understood mammalian niches, but it reports no new research findings.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review discusses the various components essential for successful tissue engineering, such as cell sources, modification methods, and supportive matrices, and highlights the need for functional synergy without reporting new experimental results.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

This study found no SARS-CoV-2 RNA in the semen and urine of a COVID-19 patient, suggesting possible viral clearance or absence in these fluids.

This study found that schizophrenia-derived neurons exhibited impaired differentiation and mitochondrial dysfunction, suggesting a potential link between these factors and neurodevelopmental processes in schizophrenia.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This study found that the GhDET2 gene plays a crucial role in cotton fiber initiation and elongation, suggesting that modifying brassinosteroid biosynthesis may enhance fiber quality or yield.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

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 the phenotype of Hedgehog/Gli-driven skin tumors in mice depends on the cell of origin, tissue context, and level of oncogenic signaling.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.
