This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

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 study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.

This study found that overexpression of sFRP4 in skin cells reduces Wnt signaling activation, leading to decreased melanocyte differentiation in regenerating hair follicles.

This study found that chronic exposure to fadrozole or finasteride during frog development induced intersex individuals, which displayed different gene expression profiles depending on the chemical used.

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.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

In this study, β-catenin overexpression in human hair outer root sheath cells increased the expression of Pitx2, which activated the follicular differentiation pathway, suggesting Pitx2's potential role as a modulator in hair growth control.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

This study found that circRNA-0100 promotes differentiation of secondary hair follicle stem cells into hair lineage in cashmere goats by sequestering miR-153-3p, which enhances KLF5 expression.

This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

This study found that COL17 plays a key role in regulating epidermal keratinocyte differentiation and proliferation, influencing the expression of differentiation markers and cellular growth in specific conditions.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

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 moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

This study found that dermal EZH2 plays a crucial role in controlling fibroblast differentiation by regulating Wnt/β-catenin and retinoic acid signaling during skin development.

In this study, adipose-derived stem cells from human scalp were successfully directed towards chondrocyte differentiation, with TGF-beta3 and BMP-6 growth factors proving effective for in vitro chondrogenesis.

This study found that Erdr1 expression was significantly reduced in the skin of patients with hair loss disorders, particularly alopecia areata, suggesting it may serve as a novel biomarker.

The study found that dermal EZH2 plays a crucial role in coordinating dermal fibroblast differentiation and epidermal development by modulating Wnt/β-catenin and retinoic acid signaling.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

This study found that mice lacking REDD1 experienced an expansion of dermal white adipose tissue through both hypertrophy and hyperplasia, suggesting a potential therapeutic target for skin adipogenesis regulation.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.
