This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This review discusses the role of oestrogens in stimulating linear bone growth and pubertal changes in both boys and girls, highlighting their influence on the growth hormone-insulin-like growth factor axis; it reports no new clinical results.

This review discusses the role of umbilical cord-derived mesenchymal stromal cells in skin rejuvenation and reports no new clinical results; it emphasizes their potential in delaying skin aging.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study reports that using activated platelet-rich plasma releasate in the preparation of bioengineered hair follicle germs enhanced follicular gene expression and significantly improved hair regeneration in vitro.

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

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.

This study found that serum 25-hydroxyvitamin D was inversely associated with serum ferritin levels in Korean men, positively associated in premenopausal women, and not associated in postmenopausal women.

This study investigated protein expression changes during mouse hair follicle cycles and suggested their involvement in biological networks, potentially identifying targets for hair disease therapy.

This review discusses the effects and selection criteria of different progestogens in various treatments but reports no direct clinical comparisons of their metabolic effects.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

Non-thermal plasma helps hair grow by improving the area around hair follicles.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.

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 clinical features and treatment options for hyperandrogenism in women and does not report new findings, highlighting current practices in diagnosis and management.

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

This review discusses the regulation of hair growth, causes of excessive androgen secretion, and current safe solutions for hyperandrogenism manifestations in women but reports no new clinical results.

This study found that a collagen patch made with fibroblast-derived extracellular matrix (fdECM) extracted from human lung fibroblasts enhanced wound healing by promoting wound contraction, angiogenesis, and skin remodeling in full-thickness skin wound models, including those with diabetic ulcers.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.

In this study, researchers prepared a humanized CXCL12 antibody for alopecia areata treatment, finding it significantly delayed disease onset in mice and reduced immune cell activation, suggesting potential as an immune modulatory therapy.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This study identified 21 novel circular RNAs in cashmere goats, with nine significantly more expressed during the anagen phase of hair follicle growth, suggesting roles in hair regeneration and cashmere yield enhancement.

In this study, bromocriptine's inhibition of prolactin promoted secondary follicle development during anagen in cashmere goats, likely via changes in specific gene expressions, despite not affecting fiber characteristics or primary follicle activity.

This study suggests that porphyra-334 may have antiaging properties, promoting collagen synthesis, improving periorbital wrinkles, and supporting hair follicle growth through gene regulation.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

In this study, male Koreans with androgenetic alopecia showed a significant association with hypertension, whereas females did not demonstrate this link.
