The new device improves human hair follicle cell growth and differentiation.

This study found that strontium cannot fully substitute for calcium in oat seedling root and root hair growth, though it may help mitigate toxic effects from other ions.

This study found that maize root hairs respond differently to cold stress based on severity, with mild cold allowing limited growth through adaptive remodeling, while severe cold causes more pronounced inhibition and prioritizes stress defense, affecting transcriptome and morphology.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This study used multi-omics analysis to explore how wheat roots adapt to temperature stress, revealing that distinct hormonal signaling pathways are linked to iron homeostasis and drive root morphological changes, supporting the idea of an 'iron-dependent hormonal trade-off' model.

This study found that the Nod factor from Rhizobium meliloti, particularly at concentrations of 10-8 and 10-7 M, induced specific membrane depolarization and root-hair deformation in Medicago sativa, depending on the stage of cell differentiation.

In this study, researchers found that increased hydrogen sulfide levels in Arabidopsis disrupted actin dynamics through S-sulfhydration, leading to the depolymerization of actin filaments and inhibited root hair growth.

The study observed that in women, the number of hair follicles with an internal root sheath decreases with age in the parietal region, also hinting at a reduction in hair follicle and shaft width.

This study found that combining IGF-1 and EGF in specific concentrations significantly stimulated hair follicle growth in vitro for primary follicles from Liaoning cashmere goats.

In this study, the researchers optimized a method for culturing melanocyte precursors from hair follicles and found that 1,25-dihydroxyvitamin D3 significantly promotes their differentiation and melanin synthesis.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that when human hair follicles were grafted onto mice, they progressed through dystrophic stages and returned to normal growth, with stem cells aiding in recovery.

This study observed that in vitro cocultures of hair follicle cells with dermal fibroblasts or hair papilla cells enhanced proliferation and differentiation of outer root sheath cells but did not mimic hair-type differentiation.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

Calretinin identifies the companion cell layer in human hair follicles.

This study concludes that loose anagen hair can develop in adulthood and may be difficult to distinguish from telogen hair loss, with pathologic findings offering limited diagnostic insights.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This study observed that hair properties vary by ethnicity, influenced by genetic, environmental, and cultural factors, and noted that ethnicity-dependent differences in surface charge and other properties warrant further investigation.

This study observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

This review discusses recent physiological and genetic advances in understanding tip growth in Arabidopsis thaliana root hairs and reports no new experimental results.

This study reviewed scalp biopsies from African-American patients, identifying distinct features and diagnostic clues for scarring alopecia types such as traction alopecia and central centrifugal cicatricial alopecia.

In this study, researchers examined the skin of neonatal rabbits and found that most hair follicles were in the terminal stage, with hair shafts protruding through the epidermis, but noted the absence of sweat glands.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

This case report describes an adolescent female with a linear array of trichoepitheliomas on her left neck, highlighting the clinical presentation of this benign tumor.

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