research Cutaneous Epithelial Stem Cells
Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.
research Investigation of differences in follicular penetration of particle-and nonparticle-containing emulsions by laser scanning microscopy
Particles similar in size to hair cells penetrate hair follicles better.
research Proopiomelanocortin expression in the skin during induced hair growth in mice
research Transient activation of β-catenin signalling in adult mouse epidermis is sufficient to induce new hair follicles but continuous activation is required to maintain hair follicle tumours
Temporary activation of β-catenin can create new hair follicles, but ongoing activation is needed to keep hair follicle tumors.
research Faculty Opinions recommendation of De novo production of dermal papilla cells during the anagen phase of the hair cycle.
New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
research Tenascin expression in normal human adult skin and skin appendage tumours
Tenascin is present in normal skin and certain skin tumors but not in sebaceous glands or their tumors.
research Observation of cultured amelanotic melanocytes from hair follicles by atomic force microscopy
Amelanotic melanocytes from hair follicles are immature and likely don't transfer melanosomes to keratinocytes.
research Nestin as a marker of unipotent epithelial progenitor cell differentiation into outer root sheath keratinocytes in embryonic and adult hair follicles
Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.
research Compartmentalized Epidermal Activation of β-Catenin Differentially Affects Lineage Reprogramming and Underlies Tumor Heterogeneity
Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.
research Linear trichoepithelioma on the neck of a 15-year-old girl
A 15-year-old girl has a benign skin tumor on her neck.
research Hair structure anatomy and comparative anatomy1 1Dedicated to the memory of the late Dr. R. E. Rivett whose untimely death prevented his role in co-authorship.
Human hair is complex and grows in cycles starting from embryonic life.
research Epidermal Development in Mammals: Key Regulators, Signals from Beneath, and Stem Cells
Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.
research Microneedles-A new paradigm in transdermal delivery of therapeutic agents
Microneedles offer a painless, effective way to deliver drugs through the skin.
research The enhancement of dermal papilla cell aggregation by extracellular matrix proteins through effects on cell–substratum adhesivity and cell motility
Skin cell clumping for hair growth is improved by a protein called fibronectin, which helps cells stick and move better.
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.
research Epithelial Fibronectin meshwork controls skin regeneration
Fibronectin is essential for hair follicle regeneration by supporting stem cells.
research Keratin 79 identifies a novel population of migratory epithelial cells that initiates hair canal morphogenesis and regeneration
Keratin 79 cells help form and regenerate hair canals.
research A single type of progenitor cell maintains normal epidermis
One type of progenitor cell can maintain normal skin in mice.
research INTRODUCING THEORY LINKING GENESIS OF HAIR SHAFT BIPOLARITY WITH ARRECTOR PILI MUSCLE PROXIMAL ATTACHMENT
The document suggests that human hair has electrical charges because of a gap in nerve cell coverage that affects electromagnetic radiation.
research Apoptotic cells may drive cell death in hair follicles during their regression cycle
Apoptotic cells help cause hair follicle cell death during regression.
research Hair Follicles Guide Nerve Migration In Vitro and In Vivo in Tissue-Engineered Skin
Hair follicles help guide nerve growth, improving touch recovery in skin grafts.
research Molecular Control of Epithelial–Mesenchymal Interactions During Hair Follicle Cycling
Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.
research Epidermal cyst containing numerous spherules of keratin
The cyst had unusual keratin spherules and resembled bone marrow.
research Manipulation of stem cell proliferation and lineage commitment:visualisation of label-retaining cells in wholemounts of mouse epidermis
Stem cell behavior varies with stimuli, and lineage changes can happen without affecting stem cell division.
research Intercellular junctions in normal epidermis
Desmosomal adhesion is essential for healthy skin structure and function.
research Basal Lamina Changes During Tissue Interactions in Hair Follicles—An In Vitro Study of Normal Dermal Papillae and Vitamin A-Induced Glandular Morphogenesis
research [Difference between the hair follicle cell and epidermal keratinocyte in vitro].
Hair follicle cells and skin cells differ in keratinization and other features.
research Linkage of Monilethrix to the Trichocyte and Epithelial Keratin Gene Cluster on 12q11-q13
research Clinicopathological features and expression of four keratins (K10, K14, K17 and K19) in six cases of eruptive vellus hair cysts
Eruptive vellus hair cysts likely originate from the infrainfundibulum and sebaceous duct.
