This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This study found that a gain-of-function mutation in the TRPV3 channel leads to altered hair development in DS-Nh mice by affecting the anagen and telogen phases, highlighting TRPV3's role in hair growth regulation.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

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 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 study reported that specific non-coding RNAs may regulate the hair follicle cycle in Angora rabbits by acting as competitive endogenous RNAs, enhancing understanding of ncRNA roles in hair growth.

This study observed that rat vibrissa hair follicles cultured in vitro showed morphological changes suggesting cyclical activity but remained blocked in the pro-anagen stage.

This study found that the DNA methylation status of skin samples from cashmere goats was higher during the telogen stage compared to the anagen stage, identifying genes potentially important for hair follicle development and growth.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

This study found that morroniside enhanced hair follicle growth and transition through the Wnt/β-catenin signaling pathway in a mouse model, suggesting its potential as a treatment for hair loss.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

This study developed a mouse model to monitor hair follicle cycling macroscopically through live bioluminescence imaging, enabling detailed analysis of hair cycle and propagation dynamics influenced by environmental factors.

This study found that irregular menstrual cycles in Brazilian adolescents were significantly associated with a higher occurrence of metabolic syndrome and polycystic ovary syndrome indicators.

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 study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

This study found that overexpression of sPLA2-IIA in homozygous mice resulted in cyclic alopecia, a halt in hair follicle cycling, and impaired wound healing due to complete loss of hair follicle stem cells.

This review of murine studies reports that γ-rays affect hair follicle pigmentation in mice throughout the hair cycle, while effects on hair structure may be obscured by aging.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.
