This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This study identified four ferroptosis-related genes, SLC40A1, LCN2, CREB5, and SLC7A11, as potential diagnostic markers for alopecia areata, revealing reduced expression in affected patients compared to controls, with a predictive model showing high accuracy in differentiating the condition.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

This study found that stabilizing HIF1A in hair follicle cells promoted a shift to glycolysis, potentially reducing oxidative stress and promoting hair growth, particularly in balding dermal papilla cells.

Vitamin D3 affects cell differentiation in specific skin areas.

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 established a Krt24-CreERT2 mouse line targeting outer bulge hair follicle stem cells, finding these cells crucial for hair follicle development and repair, particularly following ionizing radiation exposure.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

The abstract reports that non-cultured cellular grafting has become a prevalent and cost-effective method for treating stable vitiligo, with safety and effectiveness confirmed by two decades of studies. It critiques strict legislative oversight, suggesting it might unnecessarily increase costs and limit patient access.

This study investigated the histogenetic relationship between basal cell carcinoma and hair follicles, revealing specific staining patterns of a monoclonal antibody in different skin tissues.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This study demonstrated that plucked human hair follicles cultured in a collagen gel matrix developed spike-like structures, suggesting a useful method to study outer root sheath cell growth and differentiation in vitro.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This review discusses how neuroendocrine regulation affects human hair follicles and suggests potential therapeutic targets, but it reports no new clinical results.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

This study found that Gnαs and Gnα11 proteins were significantly more expressed in the skin of black sheep compared to white sheep, suggesting their role in coat color regulation.

In this study, low-level light therapy increased the proliferation and activation of dermal papilla cells, which in turn may enhance the growth of outer root sheath keratinocytes, suggesting potential mechanisms for improving hair follicle interaction.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

In this study, the authors observed that cell-mediated immune mechanisms may be involved in the pathogenesis of benign follicular mucinosis, based on the cellular and immunological characteristics of two patient cases.

This study found that Edar signaling plays a role in regulating the hair cycle and apoptosis in hair follicle keratinocytes during the catagen phase in mice.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

This study successfully developed 3D hair follicle organoids from neonatal mouse epidermal and dermal cells, showing structural and molecular resemblance to native anagen hair follicles.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

This report diagnosed a mass below a dog's eye as desmoplastic tricholemmoma based on histopathological and immunohistochemical findings.

This study found that Runx3 deficiency in mice affects hair type and shape, suggesting it may regulate hair formation through interactions between dermal and epidermal layers.
