Microscopy of keratin filaments inside cells. Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates.
Keratin protein expression within the various layers and anatomic locations of the human integumentary system Keratin type Location of expression 1: Suprabasal epidermis of skin 2 (2e) Granular layer: 3: Cornea: 4: Suprabasal epidermis of mucosa 5: Basal layer: 6a: Suprabasal palmoplantar skin 6b: Basal palmoplantar skin Nail bed Hair follicle ...
They accomplish this in two ways. First, they are keratinocytes (keratin cells) whose primary function is to produce keratin, a strong structural protein. The keratin accumulates within each spinous cell as it moves upward through the epidermis layers, until the cell is almost completely filled with hardening keratin (keratinisation). [3]

Civatte body. A Civatte body (named after the French dermatologist Achille Civatte, 1877–1956) [36] is a damaged basal keratinocyte that has undergone apoptosis, and consist largely of keratin intermediate filaments, and are almost invariably covered with immunoglobulins, mainly IgM. [37]
The first sequences of keratins revealed that keratins could be grouped into two categories based on their sequence homologies. [1] [2] These two groups of keratins were named as type I and type II keratins. [2]
She adds that you want to look for key ingredients such as keratin, collagen, amino acids, hyaluronic acid, vitamin E, and niacinamide (B3), which can support hair, nails, and skin.
The thickness of the stratum corneum varies throughout the body. In the palms of the hands and the soles of the feet (sometimes knees, elbows, [ 9 ] knuckles,) this layer is stabilized and built by the stratum lucidum (clear phase) which allows the cells to concentrate keratin and toughen them before they rise into a typically thicker, more ...
