Brandt's hedgehog has thick skin on its back and many glands near its nostrils.
research Immunolocalization of Scaffoldin, a Trichohyalin‐Like Protein, in the Epidermis of the Chicken Embryo
Scaffoldin helps form hard skin structures in chicken embryos.
research Morphogenesis- and Hair Cycle-dependent Expression of Trichohyalin, Peptidylarginine Deiminase Type III and Deiminated Trichohyalin in Rat Dorsal Skin Hair Follicles
THH and PAD type III appear together early in hair growth, but deiminated THH appears later, suggesting another factor is involved.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Structural features of the α-type filaments of the inner root sheath cells of the guinea pig hair follicle
α-type filaments in guinea pig hair follicles have unique structural features.
research Expression of SPARC (secreted protein acidic rich in cysteine) throughout the hair cycle in rats
SPARC likely aids in tissue remodeling during the hair cycle, not in starting new hair growth phases.
research The Dermal Papilla and Maintenance of Hair Growth
research The role of hair follicle dermal sheath cells in rat skin wound healing:an experimental study
Hair follicle dermal sheath cells speed up skin wound healing.
research Essential Role of Polarity Protein Par3 for Epidermal Homeostasis through Regulation of Barrier Function, Keratinocyte Differentiation, and Stem Cell Maintenance
The protein Par3 is crucial for healthy skin, affecting the skin barrier, cell differentiation, and stem cell maintenance.
research Pili Annulati with Multiple Fragile Hairs
Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.
research Keratinisation status and cytokeratins of the human Meibomian gland epithelium
Hyper-keratinisation in Meibomian glands contributes to gland dysfunction.
research Coexisting trichorrhexis nodosa and pili annulati: a case report of hair shaft abnormalities in a syrian family
A 23-year-old Syrian woman has two rare hair disorders, and avoiding hair treatments plus using vitamins and minoxidil may help.
research Bletilla striata polysaccharide (BSP) promotes hair growth and suppresses oxidative stress and senescence of dermal papilla cells by inhibiting prostaglandin-endoperoxide synthase 2 (PTGS2)
research Immunohistochemical analysis of tissue remodelling during the anagen-catagen transition of the human hair follicle
The inner root sheath is crucial for hair follicle stability during the transition from growth to involution.
research Three-Dimensional Analysis of Cell Division Orientation in Epidermal Basal Layer Using Intravital Two-Photon Microscopy
Cell division orientation varies by body site and is linked to epidermal thickness and cell density.
research Electron microscope observations on the glassy layer of the hair follicle*1
The glassy layer of hair follicles has different fibril sizes and arrangements in guinea pigs and young mice.

People with pemphigus vulgaris and pemphigus foliaceus often have smaller sebaceous glands on their scalp.
research Immunoperoxidase anti-keratin staining of epidermal and pilar cysts
Epidermal cysts come from the skin, while pilar cysts come from hair follicles.
