This study found that epidermal growth factor decreased hair growth rate and altered hair characteristics in neonatal mice, with some effects persisting into subsequent hair generations.

This article reviews the autonomous functioning and complex interactions within hair follicles, emphasizing their unique composition and differentiation pathways, but does not report new research findings.

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

This study found that epidermal growth factor treatment in male mice delayed normal skin development, inhibiting hair growth and follicle development by maintaining birth-level cell proliferation and differentiation for several days.

This review discusses the safety and efficacy of bimatoprost ophthalmic solution 0.03% for enhancing eyelash growth by influencing the eyelash hair cycle and follicles, and it reports no new results.

This article discusses the potential role of a local skin POMC system in the murine hair cycle and cutaneous stress responses, with no new results presented.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

Hair differentiation starts earlier than thought, involving multiple type-II keratins.

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 research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

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

This study found that trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.

In this study, heparin was found to exert dose- and hair cycle-dependent effects on skin epithelial cells in mice, affecting hair follicle development and protein synthesis differently based on its administration method.

This study found that plasmacytoid dendritic cells are central to the pathogenesis of alopecia areata, suggesting they may help differentiate it from trichotillomania and androgenetic alopecia.

This study reports that using laser microdissection to isolate telogen hair follicles significantly improves DNA extraction efficiency for STR typing, reducing contamination from keratin.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This study found that oral administration of l-cystine with vitamin B6 effectively prevents environmental cigarette smoke-induced alopecia in mice by reducing hair bulb cell apoptosis.

This study found that daily injections of basic and acidic fibroblast growth factor in newborn mice significantly delayed hair follicle development within the treatment area, while epidermal growth factor affected the entire body coat and caused skin hyperkeratinization.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This report describes two cases of sustained hair repigmentation related to porphyria cutanea tarda, though the underlying mechanism remains unclear.

This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

Tiny particles carrying roxithromycin can effectively target and deliver the drug to hair follicles without irritation.

This study found significant variation in tissue mutant load in individuals with the T8993G mutation, which complicates genetic counseling and may inform genotype-phenotype correlations, especially using hair bulb mtDNA analysis.

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.
