research The hair cycle and its regulation
Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
research LB1011 Oncogenic ras mutation induces spatiotemporally specific tissue deformation through converting fluctuated into sustained ERK activation
A specific mutation in Kras causes abnormal tissue changes by making a cell signal continuously active, which disrupts normal cell coordination.
research Spatio-temporal regulation of gene expression defines subpopulations of epidermal stem cells
Different types of skin stem cells can change and adapt, which is important for developing new treatments.
research Phototrichogram Analysis of Japanese Female Subjects with Chronic Diffuse Hair Loss
Phototrichogram and hair diameter measurements are effective, noninvasive ways to assess hair growth and detect early hair loss, with the most common pattern being reduced hair density.
research Time-course RNA-seq analysis reveals stage-specific and melatonin-triggered gene expression patterns during the hair follicle growth cycle in Capra hircus
Melatonin affects gene expression in goat hair follicles, potentially increasing cashmere production.
research Modulation of sonic hedgehog, patched and patched-2 expression by epidermal growth factor signaling in mouse hair follicle formation
research Androgenetic Alopecia: Analysis of Proliferation and Apoptosis
research Overexpression of insulin-like growth factor-1 induces hyperplasia, dermal abnormalities, and spontaneous tumor formation in transgenic mice
Overexpressing IGF-1 in mice leads to skin abnormalities and tumors.
research Pubertal Development
Puberty involves complex hormonal changes, varies by gender and ethnicity, and requires careful monitoring for abnormalities.
research Micro-mechanical approaches to characterize tip growth: Insights into Root Hair Elasto-Viscoplastic Properties
Root hair stiffness is mainly influenced by tip compression and turgor pressure.
research Growth pattern and turnover of carbon and nitrogen measured by stable isotope ratios in the hair of sika deer (Cervus nippon)
Shoulder guard hair best shows sika deer's diet.
research The clock within
The circadian clock in skin cells controls their growth and rest cycles.
research [Effects of immune responses mediated by topological structures of three-dimensional bioprinted scaffolds on hair follicle cycle in mice].
Moderate immune responses help hair growth, while excessive responses slow it down.
research Mutant laboratory mice with abnormalities in hair follicle morphogenesis, cycling, and/or structure: An update
The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.
research Hair Follicle Development and Hair Growth from Defined Cell Populations Grafted onto Nude Mice
research Reporting Live from the Epidermal Stem Cell Compartment!
The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.
research Determination of Secondary Follicle Characteristics, Density, Activity, and Hoxc13 Expression Pattern of Hexi Cashmere Goats Breed
Hexi cashmere goats' hair growth varies by stage, with Hoxc13 linked to hair activity.
research Intensive stress impedes hair follicle growth through triggering cell cycle arrest of hair follicle stem cells
Intense stress stops hair growth by halting hair follicle stem cell activity.
research Additional file 12 of Time-course RNA-seq analysis reveals stage-specific and melatonin-triggered gene expression patterns during the hair follicle growth cycle in Capra hircus
Melatonin affects when and how goat hair follicle genes turn on and off during growth cycles.
research Author response: Intercellular propagation of extracellular signal-regulated kinase activation revealed by in vivo imaging of mouse skin
ERK activation spreads between cells, influencing cell division and wound healing.
research 702 dsRNA induces ectopic KRT9 expression via WNT/β-catenin-mediated signaling

research PDGF isoforms induce and maintain anagen phase of murine hair follicles
PDGF isoforms can promote and sustain hair growth.
research sm“FISH”ing for Hedgehog
Hedgehog signaling controls hair follicle development and can affect skin cancer growth.
research Androgenetic Alopecia
Most older adults experience pattern hair loss due to shrinking hair follicles, with men and women showing different balding patterns.
research Differential expression of a gene homologous to a G-α protein gene in neonatal mouse skin during development of hair follicles
