This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This study found that the mK6alpha and mK6beta genes in mice are regulated differently at the mRNA level, with implications for understanding K6 gene evolution and function in mammals.

A specific gene mutation causes woolly hair and hair loss.

HGF activator helps convert HGF to its active form, promoting hair growth.

Immunocompromised patients can develop skin and hair issues due to a virus.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

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 found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

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 found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.

This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study found that the zinc transporter ZIP10 is crucial for epidermal development, as it influences the activity of p63, promoting epidermal morphogenesis.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

Hair follicles grow hair and release it through the skin.

Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.

This study found that in scarring alopecia, stem cells are differentially localized, suggesting that both inner and outer root sheath stem cells, rather than just follicular bulge stem cells, are involved.

This case report identifies a potential new syndrome characterized by trichoepitheliomas and alopecia, which may be associated with myasthenia gravis.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

MCSP may help identify and regulate skin stem cells, affecting hair growth and regeneration.

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 observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This study found that dermal papilla cells from beard and axillary hair follicles can produce androgen-dependent factors that stimulate proliferation in adjacent follicular epithelial cells under testosterone influence.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.
