240-270 / 1000+ resultsresearch Expression of extracellular matrix in hair follicle mesenchyme in alopecia areata
Alopecia areata may involve disrupted mesenchymal function in hair follicles.
research Human hair follicles display a functional equivalent of the hypothalamic‐pituitary‐adrenal (HPA) axis and synthesize cortisol
Human hair follicles can produce cortisol like the body's stress response system.
research New frontiers in human hair follicle (neuro‐)endocrinology
Human scalp hair follicles can produce and respond to several hormones, affecting hair growth and pigmentation.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research In brief
Pilomatricomas don't follow the usual hair follicle cell differentiation process.
research Androgens and the hair follicle. Cultured human dermal papilla cells as a model system.
research Phenotypic modulation of human hair matrix cells (trichocytes) by environmental influence in vitro and in vivo.
Human hair cells can change based on their environment, especially interactions with certain skin cells.
research Hair curvature: a natural dialectic and review
The document concludes that hair curvature can be explained by the growth patterns caused by the shape and separation of cells in the hair follicle and is affected by specific molecular pathways.
research Mesenchyme governs hair follicle induction
The mesenchyme can start hair growth, but the exact signal that causes this is still unknown.
research Locations of synthesis of hair structural proteins in human anagen follicles
Hair structural proteins are synthesized sequentially in specific cells, offering a new way to study hair proteins and defects.
research Follicular dermal papilla structures by organization of epithelial and mesenchymal cells in interfacial polyelectrolyte complex fibers
Scientists created 3D hair-like structures that could help study hair growth and test treatments.
research Hierarchical patterning modes orchestrate hair follicle morphogenesis
Hair follicle patterns form through a mix of self-organization and signaling interactions.
research An eGFP-Col4a2 mouse model reveals basement membrane dynamics underlying hair follicle morphogenesis
Basement membrane changes are crucial for hair follicle development.
research Pilomatricoma can differentiate not only towards hair matrix and hair cortex, but also follicular infundibulum, outer root sheath and hair bulge
Pilomatricoma can develop into various hair-related structures.
research 839 Spatiotemporal antagonism in mesenchymal-epithelial Signaling in sweat versus hair fate decision
Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
research Fine structure of marsupial hairs, with emphasis on trichohyalin and the structure of the inner root sheath
Marsupial hair structure and keratin distribution are similar to placental mammals.
research Differentiation and Apoptosis in Pilomatrixoma
Pilomatrixoma involves abnormal hair keratin production and cell death, causing debris and cysts.
research A single-cell transcriptomic atlas elucidates the hair cycle and apoptosis mechanisms in goat hair follicles
The study maps goat hair follicle cells, revealing key genes and pathways involved in hair growth and cell death.
research Connective tissue sheath of hair follicle is a major source of dermal type I procollagen in human scalp
The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.
research The HOXC13-controlled expression of early hair keratin genes in the human hair follicle does not involve TALE proteins MEIS and PREP as cofactors
research A quantitative technique to analyze and evaluate microstructures of skin hair follicles based on mueller matrix polarimetry
