Keratinized surfaces are protected from absorption by keratin protein. Keratinized epithelium has keratin deposited on the surface which makes it impermeable and dry. Examples of keratinized stratified squamous epithelium include skin, the epidermis of the palm of the hand, and the sole of the foot, [3] and the masticatory mucosa.
Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue. [ 8 ] [ 9 ] Keratinization is the differentiation of keratinocytes in the stratum granulosum into nonvital surface cells or squames to form the stratum corneum.
Stratified squamous epithelium: is simulated by oral keratinocytes cultured in a medium containing keratinocyte growth factors such as the epidermal growth factor (EGF). [ 1 ] To obtain the best results, the type and origin of the fibroblasts and keratinocytes used in oral mucosa tissue engineering are important factors to hold into account.
While the junctional epithelium is a stratified and thin epithelium that is attached to the tooth surface, the epithelium of the gingival sulcus is stratified squamous and thicker non-keratinised. Presence of Rete Pegs which may be prominent epithelial ridges can also be found in the gingival epithelium that is a stratified squamous, thick and ...
In structure, it consists of a keratinized stratified squamous epithelium; four types of cells: keratinocytes, melanocytes, Merkel cells, and Langerhans cells. The predominant cell keratinocyte , which produces keratin , a fibrous protein that aids in skin protection, is responsible for the formation of the epidermal water barrier by making and ...
Tissue mass is defined at 3.3 kg (ICRP-89, ICRP110) and addresses the skin's epidermis, dermis, hair follicles, and glands. The cell data is extracted from 'The Human Cell Count and Cell Size Distribution', [ 17 ] [ 18 ] Tissue-Table tab in the Supporting Information SO1 Dataset (xlsx).
Non-keratinized squamous epithelium, including cornea and transitional epithelium [6] Cytokeratin 7: A subgroup of glandular epithelia and their tumors [6] Transitional epithelium and transitional carcinoma [6] Cytokeratin 8: Glandular epithelia of the digestive, respiratory and urogenital tracts, both endocrine and exocrine cells, as well as ...
The anocutaneous line represents the transition point from non-keratinized stratified squamous epithelium of the anal canal to keratinized stratified squamous epithelium of the anus and perianal skin. [3] In live persons, the color of the line is white, hence the alternative name. It is named for John Hilton. [4]
