60-90 / 1000+ resultsresearch Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research 1378 Identification of two distinct stem cell clusters, Lrig1-derived and Wnt/CD44-dependent, in corneal epithelium
The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.
research Defining the complex epithelia that comprise the canine claw with molecular markers of differentiation
Canine claws have complex structures with different keratin types, similar to hair and nails.
research Ultrastructure of the contrasting types of keratinization seen in the tail epidermis of the laboratory mouseMus musculus
Mouse tail skin has different keratinization near hair follicles and scales.
research Epidermal Barrier
Healthy skin prevents water loss and protects against threats.
research Embryologic layers in dermatology: Developmental checkpoint disorders, diagnostic insight, and regenerative futures
Understanding embryologic layers improves skin disorder diagnosis and supports developing targeted therapies.
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 Dermo‐epidermal interactions in reptilian scales: Speculations on the evolution of scales, feathers, and hairs
Reptilian scales, feathers, and hairs evolved from changes in skin cell interactions.
research Normal histology of the skin
The skin has two main layers, the epidermis and dermis, which work together and are essential for diagnosing skin conditions.
research Mechanical stiffness across skin layers in human: a pilot study
The epidermis is the stiffest skin layer.
research Trichilemmoma.Cell biology of the normal human outer root sheath.
The outer root sheath in hair follicles changes during growth, with different keratinization processes in its layers.
research Expression of hair keratins in the adult nail unit: an immunohistochemical analysis of the onychogenesis in the proximal nail fold, matrix and nail bed
The ventral matrix is the main source of the nail plate.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
research The structure of the cornified claw sheath in the domesticated cat (Felis catus): implications for the claw‐shedding mechanism and the evolution of cornified digital end organs
Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.
research Structure of canine skin
Canine skin has two main layers: the epidermis and dermis, with a supportive subcutis layer.
research Anatomy and Physiology of the Skin
The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.
research Regeneration of Epidermal and Dental Tissues, Lens and Cornea
Most vertebrates can regenerate skin, nails, and corneas, but only some can regenerate teeth and lenses.
research Growth and differentiation of human keratinocytes cultured on eye lens capsules
Eye lens capsules are the best for growing human skin cells.
research Terrestrial vertebrates have two keratin gene clusters; striking differences in teleost fish
Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.
research Histological Study for Skin of Horse
Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.
research Cornified Epithelial Teeth of Jawless Vertebrates Contain Proteins Similar to Keratin-Associated Proteins of Mammalian Skin Appendages
Jawless vertebrates have teeth proteins similar to those in mammalian hair and nails.
research 660 Complex cellular flows shape feather follicle topology
Cell movements and forces shape feather growth in chicken skin.

Human skin has multiple layers and functions, with key roles in protection, temperature control, and appearance.
research Network analysis reveals potential mechanisms that determine the cellular identity of keratinocytes and corneal epithelial cells through the Hox/Gtl2-Dio3 miRNA axis
Hox proteins help maintain keratinocyte identity by regulating miRNA expression.
research The cell membrane complex: Three related but different cellular cohesion components of mammalian hair fibers
The cell membrane complex in mammalian hair has three distinct types with different structures and chemical properties.
research Patterns of expression of trichocytic and epithelial cytokeratins in mammalian tissues II. Concomitant and mutually exclusive synthesis of trichocytic and epithelial cytokeratins in diverse human and bovine tissues (hair follicle, nail bed and matrix, lingual papilla, thymic reticulum)
Trichocytic cytokeratins are found in hair, nails, tongue, and thymus cells, showing complex regulation in tissue development.
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.
