research Acantholytic hair casts: A dermoscopic sign of pemphigus vulgaris of the scalp
Hair casts on the scalp may be a sign of ongoing pemphigus vulgaris and could suggest a need to adjust treatment.
research [Three-dimensional culture of plucked human hair follicles inside the collagen gel matrix].
Human hair follicles can grow and form structures in a collagen gel, useful for studying hair cell growth.
research Differentiation of the basal cell epithelioma-like changes overlying dermatofibroma.
Basal cell epithelioma-like changes are most similar to normal basal cells.
research Porokeratotic adnexal ostial nevus: a paradigm of cutaneous mosaicism
PAON shows skin patterns due to genetic mosaicism.
research A Contemporary View on Felix Pinkus’ Concept of the Vitreous Membrane
The vitreous membrane in hair follicles changes shape during the hair cycle and may affect hair growth and nutrient exchange.
research Multiple follicular abnormalities in a 1‐year old cat consistent with basaloid follicular hamartomas
A one-year-old cat had multiple benign skin tumors similar to those known in humans.
research Subclinical speckled perifollicular melanosis of the scalp.
The scalp has a natural speckled pattern of increased pigment around hair follicles, possibly linked to local hormone production.
research 1299 Live imaging of keratin network in stratum granulosum reveals dynamic cytoskeletal changes during cornification in mice in vivo
The keratin network in mouse skin changes during cornification and affects the skin's protective barrier.
research An approach to disorders of pigmentation
The document concludes that pigmentation disorders in animals involve complex interactions between melanocytes and keratinocytes.
research Structural interspecies variability of mammals' hairs
Mammal hairs have different internal structures.
research Three-dimensional microvascular organization around hair follicles as revealed by FITC-dextran injection method
research DAB-labelling for collagen type III and PDGFR as control on equine skin sections.
DAB labeling effectively identifies collagen type III and PDGFR in horse skin, but may show false positives.
research FEMALE CADAVER IN THE HAN TOMB NO. 1 X-RAY DIFFRACTION STUDIES ON TWO KINDS OF FIBROUS PROTEIN
The protein structures in the hair and tendon were preserved, but their molecular arrangements changed.
research Trichoblastic Carcinoma
Trichoblastic carcinoma may be a distinct type of skin cancer different from basal cell carcinoma.
research Segmental vitiligo with confetti-like peripheral depigmentation.
Segmental vitiligo affects hair follicle melanocytes, causing small, uniform depigmented spots.
research Spatial transcriptomics of a giant pilomatricoma
The analysis of a large pilomatricoma revealed five distinct areas with different gene activity related to hair growth and tumor development.
research Histochemistry of the porcine pilosebaceous unit
Porcine and human pilosebaceous units are very similar.
research Expression of type I hair keratins in follicular tumours
Pilomatrixomas likely originate from the hair matrix due to changes in hair keratin expression.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research The Molecular Architecture for the Intermediate Filaments of Hardα-Keratin Based on the Superlattice Data Obtained from a Study of Mammals Using Synchrotron Fibre Diffraction
Hard α-keratin has a universal molecular structure with a specific superlattice arrangement.
research Ultrastructural Localization of Hair Keratins in Human Scalp Hair Shafts as Revealed by Rapid-Freezing Immunocytochemistry.
Hair keratins are mainly on macrofibrils in the cortex and in the endocuticle in the cuticle.
research DP18 A mimicker of melanoma on sun-exposed sites
Melanocytic matricoma can look like skin cancer but is usually harmless; surgery and follow-up are advised.
research Follicular mucinosis: A detailed morphologic and immunopathologic study
Benign follicular mucinosis involves immune cells attacking hair follicles.
research Trichohyalin: A structural protein of hair, tongue, nail, and epidermis
research Follicular induction and CK20+ Merkel cells overlying cutaneous focal mucinosis
Some skin growths with mucin can form hair follicles and resemble skin cancer, but a special stain can help tell them apart.
research Ultrastructural localization of hair keratin homologs in the claw of the lizard Anolis carolinensis
Lizard claws have hair-like keratins similar to those in mammals.
