In this review, extensive analysis using conditional mutant mice revealed that androgen and Wnt signals play crucial roles in the development and function of male external genitalia and erectile tissue, while also exploring various regulatory factors involved in their pathogenesis.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This study found that oral administration of cedrol, a component of ginger, improved hair regeneration and reduced hair follicle damage in cyclophosphamide-induced alopecia areata in mice more effectively than external administration, by enhancing cytokine expression and modulating key signaling pathways.

This study found that external and internal luteolin treatments reduced hair graying in model mice by mitigating age-related dysfunction in hair stem cell signaling, suggesting potential practical applications for anti-graying treatment in humans.

This review discusses the molecular mechanisms of masculinization involving androgen signaling and their roles in male embryonic development and conditions like hypospadias and prostate cancer, and reports no clinical results.

This study found that penile and clitoral differentiation in mice is influenced by androgen exposure, with penile features developing postnatally requiring prenatal and ongoing androgen presence.

This study reviewed literature on hair growth and found that external factors like pollution, stress, and nutrition can adversely affect hair, concluding that a multifactorial approach and personalized nutrition monitoring are essential for effective hair loss therapy.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.

This review discusses the interactions and signals affecting skin stem cells and their environments but reports no new experimental results; the authors highlight the need for understanding these processes to enhance tissue rejuvenation and repair.

In this study, MSC-derived magnetic nanovesicles combined with a magnetic field increased skin retention and accelerated hair follicle growth in a mouse model of hair regeneration.

This study found that external application of DGD activates the Wnt/β-catenin signaling pathway, promoting hair follicle anagen phase entry, and is a more effective and safer treatment for androgenetic alopecia in mice compared to oral administration.

This study found that D'orenone blocks root hair growth by increasing PIN2 protein abundance, leading to reduced auxin concentration, but external auxin can reverse these effects.

This study found that hair follicle stem cells in mice have an unexpected ability to adaptively determine their differentiation pathways, maintaining tissue architecture despite external stimuli.

This study demonstrated that anagen can be induced in Stat3-disrupted mice, suggesting that both Stat3-dependent and independent pathways, possibly involving PKC, mediate hair cycle progression with required PI3K activation.

In this laboratory study, researchers found that a methanol extract of peach kernel improved the growth and viability of human hair follicle dermal papilla cells, suggesting its potential efficacy for hair growth and care through cell proliferation and signaling pathways activation.

This article reviews the morphogenesis and cycling of hair follicles and the complex signaling pathways involved, without reporting new experimental results.

Diabetes can cause a variety of skin disorders, some of which may signal more serious health issues.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This abstract omits specific findings and does not provide new research results.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

This study found that calmodulin 7 (CaM7) inhibits the calcium channel CNGC14 in root hairs, affecting their polar growth by controlling calcium signaling.

This article reviews analysis techniques in LC-MS/MS and discusses the potential use of a novel in-sample calibration curve method, but reports no new experimental results.
