White sponge nevus (WSN) is an extremely rare autosomal dominant [4] condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by one or more mutations in genes coding for keratin, which causes a defect in the normal process of keratinization of the mucosa.
Keratohyalin is a protein structure found in cytoplasmic granules of the keratinocytes in the stratum granulosum of the epidermis.Keratohyalin granules (KHG) mainly consist of keratin, profilaggrin, [1] loricrin [2] and trichohyalin proteins which contribute to cornification or keratinization, the process of the formation of epidermal cornified cell envelope.
Micrograph showing low molecular weight cytokeratin (LMWCK) staining of intermediate trophoblast (placental tissue) and endometrial glands.. There are two categories of cytokeratins: the acidic type I cytokeratins and the basic or neutral type II cytokeratins.
Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs. [6] Buccal mucosa, the inside lining of the cheeks; part of the lining mucosa. Labial mucosa, the inside lining of the lips; part of the lining mucosa. [7]
This can be the result of factors such as: thickness and degree of keratinization of the epithelium, blood flow to the gums, natural pigmentation of the skin, disease, and medications. [ 3 ] Since the colour of the gums can vary, uniformity of colour is more important than the underlying color itself.
Tobacco use is associated with an increase in keratinization of the oral mucosa. [6] In extreme forms, this may manifest as leukoplakia or stomatitis nicotina (smoker's keratosis). This increased keratinization may mechanically reinforce the mucosa and reduce the tendency of ulcers to form after minor trauma, or present a more substantial ...
Because of the differences between mucous membranes and the skin (e.g., keratinizing mucosa does not have a stratum lucidum and non keratinizing mucosa does not have this layer or normally a stratum corneum or a stratum granulosum), sometimes specialized texts give slightly different definitions of hyperkeratosis in the context of mucosae.
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. Fibroblasts are usually taken from the dermis of the skin or oral mucosa. Kertinocytes can be isolated from different areas of the oral cavity (such as the palate or gingiva).
