For easier fixture insertion into Narrow apical diameter. For easier fixture insertion into New surface technology incorporation Ca2+. and NMDA inputs from neighboring cells at the basal and apical dendrites. the predetermined positions with respect to the surface of the simulated network.

HALLMARK_APICAL_SURFACE. Systematic name. M5916. Brief description. Genes encoding proteins over-represented on the apical surface of epithelial cells, e.g., important for cell polarity (apical area). Full description or abstract. Collection.

Glycosylphosphatidylinositol (GPI)-anchored proteins (GPI-APs) are a class of membrane proteins containing a soluble protein attached by a conserved glycolipid anchor to the external leaflet of the plasma membrane. In polarized epithelial cells, GPI-APs are predominantly sorted to the apical surface …

The apical (free) surface of an epithelial cell is present towards the body surface, the body cavity, the lumen of an internal organ, or a gland duct that receives cell secretions. Apical surfaces may contain cilia or microvilli.

Cell polarity is a fundamental feature of many types of cells. Epithelial cells are one example of a polarized cell type, featuring distinct 'apical', 'lateral' and 'basal' plasma membrane domains.

The epithelial tissue's apical surface is its most superficial layer. There surfaces may sport cilia or microvilli depending upon their function. Ciliated epithelia move mucus or other substances across its surface. They have an outer apical surface which is oriented [] to the exterior (e.g. of skin) or to the lumen (e.g. of intestine or glands) and a basal surface connected through basal lamina to the tissue layers beneath.

For example, saliva containing the glycoprotein mucin is a merocrine secretion.

Apical surface of the cells show many microvilli which are thick, short or elongated. 2020-02-17 An apical surface is a surface that faces the lumen which is the inner cavity of an organ. An organ of structure also has a basal side which faces the basement membrane and is commonly in contact 2020-04-29 2020-09-09 Epithelia cells are polarized with an apical surface that faces the lumen of a tube or the external environment and a basal surface that attaches to the basement membrane.

Apical Specializations Glycosylphosphatidylinositol (GPI)-anchored proteins (GPI-APs) are a class of membrane proteins containing a soluble protein attached by a conserved glycolipid anchor to the external leaflet of the plasma membrane. In polarized epithelial cells, GPI-APs are predominantly sorted to the apical surface … 2013-10-14 2020-09-09 2016-01-11 Many translated example sentences containing "apical surface" – German-English dictionary and search engine for German translations. For example, high-calcium state increased surface annexin A1, whereas high-oxalate condition increased surface α-enolase on apical membranes of renal tubular epithelial cells 12,13. The apical membrane has been argued to possess a ‘raft‐like’ character, while the basolateral surface has been compared with the plasma membrane of non‐polarized cells. Although both membrane domains contain cholesterol, it actually seems as if the basolateral surface has the higher content 34 , 35 . A single central lumen at the apical surface of epithelial cells is the feature of kidney tubules. Loss of Gal‐8 in MDCK cells, a well‐established kidney epithelial line that contributed to the understanding of many aspects of cellular polarity, disrupts the apical–basal polarity by mistargeting of Gp135.
