Lisch epithelial corneal dystrophy (LECD), also known as band-shaped and whorled microcystic dystrophy of the corneal epithelium, is a rare form of corneal dystrophy first described in 1992 by Lisch et al. [1] In one study it was linked to chromosomal region Xp22.3, with as yet unknown candidate genes.
Meesmann corneal dystrophy (MECD) is a rare hereditary autosomal dominant disease that is characterized as a type of corneal dystrophy and a keratin disease.MECD is characterized by the formation of microcysts in the outermost layer of the cornea, known as the anterior corneal epithelium.
The complexity of E-selectin ligand biology may also play a role in these discrepant in vitro and in vivo results. At least 15 different glycoprotein and glycolipid substrates for E-selectin have been described on various cancer cells, while only n-glycan Glg1 (Esl1) was shown to mediate bone metastasis. [ 40 ]
Epithelial polarity is one example of the cell polarity that is a fundamental feature of many types of cells. Epithelial cells feature distinct 'apical', 'lateral' and 'basal' plasma membrane domains. Epithelial cells connect to one another via their lateral membranes to form epithelial sheets that line cavities and surfaces throughout the ...
The glycocalyx (pl.: glycocalyces or glycocalyxes), also known as the pericellular matrix and cell coat, is a layer of glycoproteins and glycolipids which surround the cell membranes of bacteria, epithelial cells, and other cells. [1] Animal epithelial cells have a fuzz-like coating on the external surface of their plasma membranes.
Epithelial and mesenchymal cells differ in phenotype as well as function, though both share inherent plasticity. [2] Epithelial cells are closely connected to each other by tight junctions, gap junctions and adherens junctions, have an apico-basal polarity, polarization of the actin cytoskeleton and are bound by a basal lamina at
Podocytes make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place. [1] Bowman's capsule filters the blood , retaining large molecules such as proteins while smaller molecules such as water , salts , and sugars are filtered as the first step in the formation of urine .
FGF-10 helps to stimulate epithelial cell proliferation, in order make larger tooth germs. Mammalian teeth develop from ectoderm derived from the mesenchyme: oral ectoderm and neural crest. The epithelial components of the stem cells for continuously growing teeth form from tissue layers called the stellate reticulum and the suprabasal layer of ...
