This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.

This abstract provides a graphic illustrating that mice lacking the Sgk3 gene exhibit thin coats and abnormal hair, suggesting a role for Sgk3 kinase in hair follicle growth, but reports no new experimental findings.

This review examines the differentiation potential of epithelial cells from various sources in hair follicle formation, concluding that complex interactions are required for hair-specific characteristics, which were achieved in vivo but not in vitro.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

This study suggests that the MLKL-targeting inhibitor Necrosulfonamide promotes hair growth and counteracts DHT inhibition by activating Wnt signaling in hair follicle cells, revealing potential avenues for anti-alopecia drug development.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This study demonstrates that SDF-1/CXCL12 and CXCR4 signaling play a crucial role in directing the migration and positioning of melanoblasts in mouse hair follicle formation.

This study found that LEF1/TCF3 is necessary but not sufficient for TOPGAL activation in hair follicle development, indicating complex regulation in the skin.

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 study found that estrogen receptor beta, not alpha, is the main mediator of estrogen action in human skin and hair follicles, suggesting a distinct role in these tissues.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study observed that vitamin D receptor expression in certain hair follicle cells varies throughout the murine hair cycle, suggesting a potential role for 1,25-dihydroxyvitamin D3 in hair follicle biology.

This study found that Notch signaling is crucial for maintaining proper melanocyte distribution and preventing premature differentiation in the melanocyte lineage within hair follicles.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study characterizes a type II keratin intermediate filament gene family involved in early sheep follicle differentiation, detailing gene expression patterns and sequences in hair cortical cells.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that GPC1 is a crucial regulator of angiogenesis in human dermal microvascular endothelial cells, indicating its potential as a target for treating alopecia.

This study found distinct localization patterns of S100 family proteins in hair follicles, suggesting their differential roles in normal hair follicle physiology.

This study found that apoptosis, along with proliferation, plays a crucial role in shaping and extending human hair follicles by coordinating the formation and differentiation of the hair canal.

This study found that exposure to 50 Hz electromagnetic fields enhanced hair regrowth in mice by increasing stem cell proliferation and keratinocyte growth factor expression, suggesting potential benefits for hair loss treatment.

This study identified fibroblast growth factor 18 in various components of canine hair follicles and other tissues, but found no significant differences in its presence across seasons, body regions, or sexes in beagle dogs.

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

This study confirmed the localization of CK19 and vimentin in skin cells, with CK19 linked to hair growth and vimentin stabilizing fibroblast structure.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This study found that 1,25-dihydroxyvitamin D3 promotes hair growth and regeneration in mice by prolonging the anagen phase and counteracting DHT's inhibitory effects, suggesting its potential therapeutic role for androgenetic alopecia.

In this study, researchers found that knockdown of ABCA5 in primary human hair follicle keratinocytes disrupted cholesterol homeostasis and transportation, suggesting its potential role in hair growth disorders by affecting intracellular cholesterol compartmentalization and LXR-mediated transcriptional activity.
