The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This study found that loss of Ptch1 function in mouse skin's basal cells is sufficient to rapidly induce tumors resembling human basal cell carcinoma, suggesting Ptch1 as a key tumor suppressor.

This study found that transgenic mice overexpressing the BMP antagonist noggin showed increased hair follicle size and altered hair type, linked to changes in cell proliferation and gene expression.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.

This study found that Activin B at 10 ng/mL may promote vibrissae follicle growth in mice by enhancing hair matrix cell proliferation and cell cycle progression via ERK signaling pathways.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

This study investigated the effects of cedrol on colorectal cancer and found that it inhibited cell proliferation and induced cell cycle arrest and apoptosis in cell models, while in vivo, it suppressed cancer progression and improved survival at a well-tolerated dose.

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 review discusses the complex role of Runx family genes in regulating stem cells in blood and skin tissues and reports no new experimental results.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

This study reported the expression patterns and potential functions of long non-coding RNAs in the hair follicle cycle of yak, with insights into their sequence conservation between yak and cashmere goat.

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 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 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 the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

In this study, researchers established three specific cell lines from Cashmere goat hair follicles and found that cytokeratin 13 might be a novel biomarker for identifying dermal sheath cells.

In this study, researchers found that while blocking either glycolysis or glutaminolysis in cancer cells did not prevent tumor growth due to metabolic flexibility, simultaneous inhibition of both pathways hindered carcinoma development, indicating multiple interventions may be necessary for effective metabolic manipulation in cancer treatment.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

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 canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

This review discusses the latest understanding of androgenetic alopecia, including stem cell niches in hair follicles, and highlights emerging treatments like growth factors and platelet-rich plasma without new clinical findings.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.
