research Exogen involves gradual release of the hair club fibre in the vibrissa follicle model
Hair sheds gradually from the follicle, with readiness to shed indicated by less attachment material.
research Expression patterns of MITF during human cutaneous embryogenesis: evidence for bulge epithelial expression and persistence of dermal melanoblasts
Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.
research Human dermal fibroblast‐derived secretory proteins for regulating nerve restoration: A bioinformatic approach
Human dermal fibroblast proteins help restore nerves during healing.
research Cyclical dermal micro-niche switching governs the morphological infradian rhythm of mouse zigzag hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
research Prostanoid receptors in anagen human hair follicles
Human hair follicles contain a complex network of prostanoid receptors that may influence hair growth.
research Basonuclin as a cell marker in the formation and cycling of the murine hair follicle
Basonuclin helps identify and track hair follicle development and cycling in mice.
research Activation of β-catenin signaling programs embryonic epidermis to hair follicle fate
Activating β-catenin can turn skin cells into hair follicles.
research Effects of transient receptor potential (TRP) channel agonists and antagonists on slowly adapting type II mechanoreceptors in the rat sinus hair follicle
TRPA1 and TRPV1 channels don't affect mechanotransduction in rat sinus hair follicles.
research Mechanical force drives the initial mesenchymal-epithelial interaction during skin organoid development
Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.
research Single follicular unit transplantation reconstructs arrector pili muscle and nerve connections and restores functional hair follicle piloerection
Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.
research Proopiomelanocortin expression in the skin during induced hair growth in mice
research Mechanical Instability of Adherens Junctions Overrides Intrinsic Quiescence of Hair Follicle Stem Cells
Weak cell junctions disrupt hair follicle stem cell rest.
research Self‐organizing hair peg‐like structures from dissociated skin progenitor cells: New insights for human hair follicle organoid engineering and Turing patterning in an asymmetric morphogenetic field
Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.
research Mouse Epidermal Neural Crest Stem Cell (EPI-NCSC) Cultures
Mouse Epidermal Neural Crest Stem Cells can become various cell types.
research EGF–FGF2 stimulates the proliferation and improves the neuronal commitment of mouse epidermal neural crest stem cells (EPI-NCSCs)
EGF–FGF2 helps mouse stem cells grow and become more like nerve cells.
research 571 Human Hair Follicles can “Taste”: Stimulation of the Bitter Taste Receptor TAS2R4 Inhibits Hair Growth Ex Vivo by Up-Regulating TGF-β2
Activating a bitter taste receptor in hair follicles can stop hair growth by increasing a specific growth factor.
research Canonical and non-canonical Wnt signaling control the regeneration of amputated rodent vibrissae follicles
Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.
research Electron Microscope Studies of the Human Epidermis The Clear Cell of Masson (Dendritic Cell or Melanocyte)
A unique skin cell similar to hair bulb melanocytes was identified, with better preservation using permanganate fixation.
research LB1774 Establishing competent morphogenetic fields for tissue pattern regeneration in skin organoids
Skin organoids can regenerate hair by forming specific cell units with certain signals.
