In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

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 study found that Anigozanthos Flavidus flower extract may improve skin elasticity and reduce wrinkles by increasing essential extracellular matrix proteins in both in vitro and in vivo settings.

This study found that combining CelluTome system and RCM is a safe and effective protocol for evaluating wound healing responses in patients with epidermolysis bullosa.

In this study, injecting Fetuin A into embryonic mouse wounds led to scar formation, suggesting the protein may play a role in scar development by promoting collagen production.

This study observed that, contrary to common belief, aged Balb/C mice showed better wound healing than younger mice despite greater weight loss, possibly due to increased T regulatory cells.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.

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 study suggests that phenotypic plasticity, including processes like dedifferentiation and transdifferentiation, plays a crucial role in cancer initiation, progression, and therapy resistance, broadening our understanding of cancer dynamics and potential treatment strategies.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

Genetic research has advanced our understanding of skin diseases, but complex conditions require an integrative approach for deeper insight.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This review discusses how vitamin D and calcium signaling are essential for wound healing by activating epidermal and hair follicle stem cells, noting that deficiencies may lead to delayed or chronic wounds.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This study suggests that the gene rs27647 polymorphism may play a role in the pathogenesis of severe acne vulgaris in post-adolescent male patients.
