This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.

This study found that Si Jun Zi Tang may have anti-aging effects in mice, linked to inhibition of the PI3K-AKT and P38 MAPK signaling pathways.

This study introduced the concept of spatiotemporal clocks to understand how different phases of mammalian wound healing are coordinated, with a focus on the spatial domains and oscillatory molecular signals involved, while highlighting the potential for regenerative therapeutic strategies.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

This study found that scalp thickness and hair follicle depth were reduced in individuals with androgenetic alopecia, and MRI signal intensity was higher compared to those without the condition.

This source redefines anti-aging medicine as "precision healthspan pharmacology," suggesting that rather than just treating diseases or accepting aging, pharmacology should focus on expanding functional capacity across various health domains, while emphasizing the importance of fundamental physiological and psychosocial health factors.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

The researchers emphasize the limited scope of existing studies on lip aging, highlighting issues that include collagen loss and the deepening of lip lines with age, and suggesting a need for further research to guide cosmetic and clinical interventions.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This narrative review highlights recent advancements in anti-ageing cosmetic procedures, emphasizing personalized interventions that improve patient outcomes and quality of life. The review synthesized evidence from 144 articles to assess the effectiveness and potential side effects of surgical and non-surgical techniques for facial rejuvenation.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

This study reports that in a rat model of myocardial infarction, Zn-Cu ion sequential therapy improved cardiac function and cardiomyocyte metabolic activity by precisely regulating ion concentrations and maintaining elevated levels of the Per2 protein, important for cellular repair.

In this study, researchers characterized the normal scalp hair properties in South Koreans, observing that hair density declined with age and varied across scalp sites, while hair thickness patterns remained relatively stable until later in life.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study found that combining microfocused ultrasound with autologous blood cell factors significantly improved skin rejuvenation compared to using microfocused ultrasound alone.
