In this review, researchers discuss the role of epigenetic modifications in epidermal stem cells' decline during skin aging and identify potential interventions targeting these disruptions, suggesting significant possibilities for antiaging strategies and dermatological treatments.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

This article reviews how chronological aging affects female scalp hair growth and suggests that multiple factors, including environmental influences, contribute to female pattern hair loss; no new clinical results are presented.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This study reviews the role of skin stem cells in aging and explores how organoids, as opposed to traditional methods, can advance research into aging skin and regenerative therapies.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

This review explores recent advancements in understanding how various physiological and psychological factors, such as stress and aging, influence epidermal stem cell populations, highlighting their importance in immune-related skin disorders and potential for clinical applications.

This study explored the decline in cashmere production in Inner Mongolian cashmere goats through RNA-seq analysis, finding that AKT1 expression and related signaling pathways are age-dependent, with peak AKT1 upregulation at 12 months aligning with peak cashmere production.

This article discusses the mechanisms and prevention of aging, particularly in facial rejuvenation, but reports no new experimental findings.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This review discusses various surgical techniques for rejuvenating the aging upper face, focusing on the assessment of individual structures and their relationships, but it reports no new clinical results.

This review considers oxidative stress effects on hair aging and emphasizes the need for dermatologists to recognize and treat factors affecting scalp and hair health, but it provides no new clinical findings.

This review discusses the effects of calorie restriction on skin aging, highlighting its potential to benefit skin health by reducing age-related and photo-induced changes, although the impact of certain diets remains unexplored.

Benign Prostatic Hyperplasia may be caused by changes in how the body processes male hormones.

This article discusses the role of androgens in hair follicle changes, explaining how dihydrotestosterone contributes to hair thinning on the scalp, while promoting thicker facial hair in men, and reports no new clinical results.

Women's ovarian hormones and adrenal androgens change throughout life, affecting hair loss and health.

In this descriptive study, elderly patients most commonly presented with skin wrinkling, xerosis, and eczematous conditions, highlighting the difficulty in distinguishing normal age-related from pathological skin changes.

This study found that mice with a homozygous knockout of the Ten1 gene, developed through CRISPR-Cas9-mediated exon 3 deletion, exhibited telomere shortening and symptoms consistent with accelerated aging, such as reduced lifespan, skin changes, aplastic anemia, and cerebellar hypoplasia.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study found that in healthy young men, oral minoxidil at 5 mg/day led to increased carotid intima-media thickness and vascular aging, suggesting potential cardiovascular side effects at higher doses. A dose-dependent effect was observed, while dutasteride displayed a favorable vascular profile without significant changes.

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.

In this study, researchers differentiated human induced pluripotent stem cells into dermal papilla-like cells and observed gene expression dynamics during five stages of dermal differentiation, demonstrating the potential of these cells to interact with epidermal cells in functional assays.

In this article, researchers link menopause to hair follicle lifecycle changes, noting that estrogen decline, metabolic shifts, genetics, and stress can contribute to hair thinning and texture variation, although effects differ among women.

In this study, the authors concluded that the VCD-induced follicular depletion rat model can effectively simulate the perimenopause transition, with hormonal changes distinguishing early/mid-transition from late transition to estropause.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This review discusses the role of Foxc1 and type XVII collagen in hair follicle stem cell quiescence and aging, identifying mechanisms that relate to hair thinning and hair loss, and reports no new results.
