This review explores the physiological roles of collagen XVII in the epidermis, its involvement in stem cell maintenance, and its connections with signaling pathways, but it reports no new results.

This study found that a microneedle patch with recombinant collagen XVII significantly improved hair coverage, follicle density, and angiogenesis in an androgenic alopecia mouse model, showing potential as a novel therapeutic strategy alongside established treatments like minoxidil.

In this study, researchers found that hTERT/SV40 immortalization of human dermal fibroblasts up-regulates skin cell markers and highlights the SIRT1 and miR-93 pathways' roles in maintaining fibroblast proliferation, potentially benefiting developments in the cosmetic industry.

In this animal study, ultrasound combined with a new microbubble formulation of minoxidil increased hair growth rates and improved follicle characteristics more effectively than minoxidil alone.

This study examined the Spanish Merino breed's wool quality, identifying 74 genetic variants linked to key wool traits like fiber diameter and staple length, which could help restore the breed's potential for producing high-quality wool.

This study found that c-Maf positive M2 macrophages may promote hypertrophic scar formation by enhancing the proliferation, migration, and extracellular matrix deposition of hypertrophic scar fibroblasts through increased TGF-β1 expression.

This study analyzed the transcriptome of the Tianzhu white yak, identifying differential transcripts that shed light on the molecular mechanisms influencing hair length growth variation in this species.

In this study, researchers analyzed 24 European Merino sheep populations to investigate genetic adaptations to climate, identifying 168 significant SNPs and related genes associated with temperature variation and environmental adaptation, focusing on traits like isothermality and pathways related to immune response and system development.

This review examines the potential and challenges of extracellular vesicles in cosmetics, noting their transformative impact despite regulatory and production hurdles; it reports no new experimental results.

Minoxidil affects collagen-related genes, potentially helping treat fibrosis.

Hair follicle stem cells have significant potential for treating various disorders.

This study found that adult dermal papilla cells guided high-passage adult keratinocytes to produce new hair fibers, suggesting potential for large-scale hair follicle bioengineering.

This study found that bimatoprost, when applied daily at a 0.03% concentration, promoted significant hair growth in C57/black 6 mice, including earlier and faster regrowth of shaved fur.

This study found that repeated use of a protein hair conditioner, followed by hot air and gamma irradiation, may lower serum collagen I and increase heat shock protein concentrations in rats, suggesting potential cumulative risks.

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.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This meeting report discusses the first symposium on natural gene therapy for skin, preceding the 41st annual meeting of the European Society for Dermatological Research, and reports no new experimental findings.

This study found that the circular RNA circCOL1A1 influences the formation of superior-quality brush hair in white goats by regulating hair follicle stem cell behavior and interacting with the miR-149-5p/CMTM3/AR axis.

Finasteride lowers prostate cancer risk but may increase high-grade tumors and sexual side effects.

This study found that triglyceride and energy metabolic pathways are crucial factors influencing wool fiber diameter in fine-wool Alpine Merino sheep, providing insights for enhancing wool quality.

This article discusses factors influencing hair greying, such as thyroid hormone levels and postmenopausal changes, and suggests lifestyle adjustments for hair health; it reports no new clinical findings.

This abstract suggests that cost barriers limit the application of standard aesthetic procedures in developing countries, while exploring platelet-rich plasma as a potentially safer and less invasive option in geriatric aesthetics. Detailed results were not reported.

This article introduces geriatric aesthetics and discusses the potential of platelet-rich plasma as a cost-effective solution in developing countries, but reports no new clinical results.

This study found that deleting all three Tet genes in mice led to shorter hair shafts and altered hair types, with associated changes in gene expression and DNA hydroxymethylation.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

This study describes a new method for isolating intact human eccrine glands from scalp follicular units, potentially advancing research on sweat gland physiology.
