This study found that estrogen treatment induced premature catagen and apoptosis in hair follicles of wild-type mice, while having no effect on mice lacking estrogen receptor α.

This study found that Wnt10b promotes the proliferation of hair follicle stem cells and hair precortex cells, revealing them as target cells in Wnt10b-induced hair follicle regeneration.

This study found that estrogen can cause reversible suppression of the hair cycle by inducing premature catagen and maintaining the telogen phase without damaging the hair follicle stem cell niche or the signature gene expressions of dermal papilla cells.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

Inhibiting Bmp signaling disrupts hair growth and differentiation.

This study observed that deleting ARNT in keratinocytes of mice reduced zigzag hair production and altered hair follicle differentiation, likely by affecting the expression of specific cyclin-dependent kinase inhibitors.

This overview examines the biology, origin, structure, and function of various cells and structures, such as the blood-retinal barrier and Merkel cells, and discusses their roles in disease pathogenesis, along with recent findings related to the lymph nodes' paracortex.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study found that dysregulation of the folliculin-p0071 interaction may lead to changes in cell adhesion and signaling, contributing to conditions like emphysema and renal cell carcinoma.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study investigated the use of 3D cell culture technology to explore hair follicle regeneration, examining the impact of the 3D cellular environment on hair follicle morphogenesis and the effects of microwell depth on spheroid formation.

This study found that m6A-circRNA-ZNF638 enhances the activation of secondary hair follicle stem cells in cashmere goats by interacting with the miR-361-5p/Wnt5a pathway.

This study found that Manganese PCA, Cinchona succirubra, and Leontopodium alpinum extracts may promote hair growth by enhancing VEGF secretion and activating the Wnt/b-catenin pathway in Human Hair Follicle Dermal Papilla Cells.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.
