This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study observed that electro-acupuncture reduced global DNA methylation and DNMT3b expression in a PCOS-like rat model, suggesting a role of hypothalamic DNA methylation in PCOS development and treatment.

This review discusses the various potential causes of hair loss in patients with inflammatory bowel disease, including telogen effluvium from disease flares, but provides no prevalence data; the authors outline a practical assessment and management approach.

This article reviews current research on animal models for hair regrowth treatments and reports no new findings; it highlights the need for studies comparing therapy efficiency and long-term safety.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

This study describes how manipulating the actin cytoskeleton, particularly through the gelsolin family proteins, may enhance regenerative healing in mammals, suggesting potential therapeutic pathways for improved wound repair.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

In this study, Nec-1s was found to promote hair growth and may target necroptosis and the Wnt/β-catenin pathway for potential treatment of hair loss.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This study found that Blumea eriantha silver nanoparticles promoted hair growth in treated animals, with activity comparable to minoxidil in terms of anagen follicle transition.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

Reduced androgens linked to kinky hair disorder and hair loss; 5a-reductase inhibitors may help.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

This article explores the potential of combining biomarkers to assess and improve treatments for chemotherapy-induced alopecia, highlighting the limited availability of data on hair follicle damage markers with and without scalp cooling.

In this study, four dogs with a novel skin disease showed clinical lesions involving verrucous, crusted papules and plaques, and responded variably to immunosuppressive therapy, suggesting an immune-mediated cause.

This narrative discusses the critical roles of zinc in both biological processes and industrial applications but provides no new research findings.

The researchers reported that conditioned media from deer antler mesenchymal stem cells may enhance hair and skin regeneration by modulating cellular responses through secretory vesicles.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

In this study, researchers demonstrated that human hair keratins can self-assemble into stable nanofibrous networks in vitro, which are compatible with human skin cells and useful for regenerative applications.

Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.

This article highlights causes of otitis externa in small animals and proposes an investigative approach; it reports no new findings.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

In this study, re-activating SOX9 in adult epidermal stem cells led to a fate switch towards hair follicle stem cell identity, with altered chromatin dynamics and oncogenic activation, contributing insights into developmental processes and cancer pathways.

This review provides an updated overview of the symptomatology, diagnosis, trichoscopy findings, and treatment options for eyebrow and eyelash alopecia, but it reports no new experimental results.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This review discusses studies on resistance training for improving PCOS symptoms and reports no new results, highlighting the need to consider diet alongside exercise and calling for more research.
