research INTRODUCING GAP IN HAIR FOLLICLE ELECTROMAGNETISM AS MECHANISM FOR THE PRESENCE OF BIPOLAR ELECTRICAL CHARGES INHERENT IN THE HUMAN HAIR SHAFT
Human hair has bipolar electrical charges because of a gap in the hair follicle's electromagnetic field.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research Characteristic Microstructure of Curved Human Hair
Curved human hair has different structures on each side, which might cause its shape and is similar to wool.
research Follicle-innervating Aδ-low threshold mechanoreceptors organize through a population-dependent mechanism
Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar cells.
research Hair—the most sophisticated biological composite material
Hair is a complex protein fiber with unique properties useful for developing hair products.
research Expression of hair-related keratins in a soft epithelium: Subpopulations of human and mouse dorsal tongue keratinocytes express keratin markers for hair-, skin- and esophageal-types of differentiation
Hoxc13 is important for hair and tongue development by controlling hair keratin genes.
research Modulation of the differentiated phenotype of keratinocytes of the hair follicle and from epidermis
Hair follicle cells need complex interactions to fully differentiate.
research Mouse Hair Cycle Expression Dynamics Modeled as Coupled Mesenchymal and Epithelial Oscillators
The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.
research Cells within the bulge region of mouse hair follicle transiently proliferate during early anagen: heterogeneity and functional differences of various hair cycles
Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.
research 732 Treatment with cyclohexyl salicylate, an olfactory receptor 2A4/7 agonist, promotes human hair follicle growth and bulge stem cell progeny expansion
Cyclohexyl salicylate promotes human hair growth and increases certain hair follicle stem cell progeny.
research A cDNA encoding the human type I hair keratin hHa1
hHb1, hHb3, and hHb6 mRNAs start expressing at the same time in hair follicles.
research Histochemistry of the human hair follicle with consideration of anagen phases I to VI
Human hair follicles have a unique cell distribution and differentiation pattern during growth.
research Dermal papilla-induced hair differentiation of adult epithelial stem cells from human skin
Dermal papilla cells help skin stem cells grow into hair.
research Transdifferentiation of corneal epithelium: evidence for a linkage between the segregation of epidermal stem cells and the induction of hair follicles during embryogenesis.
Corneal cells can transform into hair-producing skin cells when exposed to certain signals.
research 804 Human hair follicles operate core elements of a functional peripheral equivalent of the central hypothalamic-pituitary-thyroid axis
Human hair follicles have their own thyroid hormone system.
research Observation of the Microstructure of Human Hair Based on a Single Detector Optical Coherence Tomography
Chemical dyes damage hair's internal structure more than perming, as shown by a special imaging technique.
research Isolation and Characterization of a Novel Hair Follicle–Specific Gene, Hacl-1
Researchers found a new gene, hacl-1, that is active in mouse hair follicles during hair growth and may be important for hair biology.
research Ovine Hair Follicle Stem Cells Derived from Single Vibrissae Reconstitute Haired Skin
Ovine hair follicle stem cells can regenerate haired skin and may improve wool production.
research Growth of human hair follicle keratinocytes in vitro
The model successfully grew and differentiated hair follicle cells in the lab.
research The variable cell
Hairless protein is key for hair growth, cell differences cause gene expression variation, and the N-end rule pathway senses nitric oxide for protein breakdown.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
research In brief
Pilomatricomas don't follow the usual hair follicle cell differentiation process.
research Linking chromatin dynamics, cell fate plasticity, and tissue homeostasis in adult mouse hair follicle stem cells
Mouse hair follicle stem cells have a flexible chromatin state that supports skin health and hair growth.
research Functional analysis of keratin components in the mouse hair follicle inner root sheath
Keratin in mouse hair follicles is complex and plays specific roles.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research The three-dimensional microvascular and collagen fibrillar arrangements around rat vibrissa hairs as revealed by scanning electron microscopy
The lower part of rat vibrissa hair gets more blood and is well-protected for growth.
research 572 Olfactory Receptor 2A4/7 Activation by the Fragrance, Cyclohexyl Salicylate, Promotes Human Hair Follicle Growth and Stem Cell Progeny Expansion
The fragrance cyclohexyl salicylate helps promote hair growth and increase hair stem cell numbers.
research Defining Hair Follicles in the Age of Stem Cell Bioengineering
The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
