This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

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

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This study found that combining liraglutide with metformin led to greater weight loss and waist circumference reduction than either treatment alone in obese women with PCOS resistant to metformin monotherapy.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This article reviews primary cicatricial alopecias, focusing on lymphocytic forms such as chronic cutaneous lupus erythematosus, according to a classification by the North American Hair Research Society, and reports no new clinical results.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This review discusses the multi-system impacts of polycystic ovary syndrome and explores evaluation and treatment strategies, but it reports no new research findings.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.

In this study, short-term liraglutide treatment led to significant weight loss in obese women with newly diagnosed PCOS and a higher metabolic risk profile compared to metformin.

This review discusses the progress and challenges in delivering CRISPR/Cas9 systems for in vivo genome editing, highlighting current methods and opportunities for future therapeutic applications.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This study reports that oral spironolactone may be a useful and low-cost first-line treatment for hidradenitis suppurativa in women, with relatively few side effects.

This review discusses possible medication-induced hair loss and the need to exclude other confounding factors like stress and illness; it reports no new clinical findings and emphasizes careful assessment before attributing hair loss to medications.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

This study found that longer exposure to 5α-reductase inhibitors significantly increased the risk of persistent erectile dysfunction, especially in younger men exposed to finasteride.
