research Ectoin attenuates cortisone‐induced skin issues by suppression GR signaling and the UVB ‐induced overexpression of 11β‐HSD1
Ectoin helps prevent cortisone-induced skin problems and supports skin health.
research Keratin expression in basal cell carcinomas
Basal cell carcinomas likely originate from hair follicle cells or stem cells.
research Expression of the hair stem cell-specific keratin 15 in pilar tumors of the skin.
K15 staining helps distinguish basal cell carcinoma from trichoepithelioma.
research Cornification
Cornification is the process where living skin cells die to create a protective barrier, and problems with it can cause skin diseases.
research Expression of the hair stem cell-specific marker nestin in epidermal and follicular tumors.
Trichilemmoma, BCC, and SCC tumors have different stem cell marker expressions.
research Characterisation of CD4+ stem cells of the skin and their role in skin homeostasis and tumourigenesis
CD4+ skin cells may be precursors to basal cell carcinoma.
research 190 Deficiency of the Human Cysteine Protease Inhibitor Cystatin M/E Causes Hypotrichosis and Dry Skin
Not having enough cystatin M/E protein causes less hair growth and dry skin.
research Epidermal Stem Cells do not Communicate Through Gap Junctions
Epidermal stem cells don't use gap junctions to communicate.
research Focal palmoplantar callosities in non-Herlitz junctional epidermolysis bullosa
Focal palmoplantar callosities may help diagnose non-Herlitz junctional epidermolysis bullosa.
research Beyond the usual: a case of acrodermatitis enteropathica clinically resembling erythrokeratoderma variabilis
Increasing zinc intake improved skin and hair symptoms in a rare genetic disorder.
research Cytokeratin 15 expression in central, centrifugal, cicatricial alopecia: new observations in normal and diseased hair follicles
CK15 is not a reliable marker for stem cells in damaged hair follicles from patients with CCCA.
research The targeted overexpression of a Claudin mutant in the epidermis of transgenic mice elicits striking epidermal and hair follicle abnormalities
research Comparative immunohistochemical analysis suggests a conserved role of EPS8L1 in epidermal and hair follicle barriers of mammals
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 Basal cells in the epidermis and epidermal differentiation
The exact identity of skin stem cells and how skin cells differentiate is not fully known.
research The Autoimmune Regulator (AIRE), Which Is Defective in Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy Patients, Is Expressed in Human Epidermal and Follicular Keratinocytes and Associates With the Intermediate Filament Protein Cytokeratin 17
AIRE protein, defective in APECED patients, is found in skin and hair cells and interacts with cytokeratin 17.
research Keratinisation status and cytokeratins of the human Meibomian gland epithelium
Hyper-keratinisation in Meibomian glands contributes to gland dysfunction.
research Exosomes serve as a crucial mediator of epithelial–fibroblast communication during hair follicle morphogenesis in cashmere goats
Exosomes help hair follicle development in cashmere goats.
research In brief
Pilomatricomas don't follow the usual hair follicle cell differentiation process.
research Expression patterns of hair and epithelial keratins and transcription factors HOXC13, LEF1, and β‐catenin in a malignant pilomatricoma: a histological and immunohistochemical study
The malignant pilomatricoma showed strong epithelial keratin expression, suggesting it may not calcify.
research Immunologic findings in central centrifugal cicatricial alopecia
CCCA may be caused by both hair traction and an immune response.
research Hair Matrix Cyst
Hair matrix cysts are rare skin nodules with unique features, often needing surgical removal.
research 547 CDK9 Kinase Activation in Association with AFF1-SEC Initiate Epidermal Progenitor differentiation
NCSTN gene mutation causes abnormal skin cell differentiation and more inflammation, contributing to Hidradenitis Suppurativa.
research Proliferating Hybrid Follicular Tumor
A unique type of complex cyst was found on a man's scrotum.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research Cytokeratins as Markers of Follicular Differentiation
TB and BCC tumors show similar follicular differentiation patterns.
research Overexpression of the calcium sensing receptor accelerates epidermal differentiation and permeability barrier formation in vivo
Increasing calcium sensing receptor speeds up skin and hair development in mice.
research Abstract LB-039: Chronic inflammation-mediated contribution of bone marrow-derived epithelial cells and hair follicle stem cells to development of cutaneous neoplasms
Bone marrow and hair follicle cells help form skin tumors, suggesting new treatment targets.
research Multiple desmoplastic trichoepitheliomas with ossification and cholesterol deposition
A man had rare skin tumors with bone formation and cholesterol deposits.
