Define Epithelial cells. Epithelial cells synonyms, Epithelial cells pronunciation, Epithelial cells translation, English dictionary definition of Epithelial cells. n. pl. ep·i·the·li·a or ep·i·the·li·ums Membranous tissue composed of one or more
epithelial tissue- membranous tissue covering internal organs and other internal surfaces of the body epithelium endothelium- an epithelium of mesoblastic origin; a thin layer of flattened cells that lines the inside of some body cavities mesothelium- epithelium originating in the embryonic mesoderm; ...
The underside, the basal surface, of the epithelial tissue is connected to an organ or structure via a basement membrane. The basement membrane is not made up of cells but is instead composed of material that adheres epithelial cells so that they remain in place. Basement membranes are ...
cells (De Proost et al., 2009). It was also shown that ATP, released from activated NEB cells, induces a paracrine secondary Ca2+-mediated activation of the surrounding stem cell-like Clara-like cells via P2Y2receptors, a phenomenon that is now used to visualise stimulated secretion from ...
When the epithelium is composed of a single layer of cells, it is called simple epithelial tissue and those containing two or more layers of cells are called stratified epithelial tissues. One particular type is called pseudostratified because a single layer of cells having...
The word tissue is derived from a Latin word meaningto weave.Cellsthat make up tissues are sometimes 'woven' together with extracellular fibers. Likewise, a tissue can sometimes be held together by a sticky substance that coats its cells. There are four main categories of tissues: epithelial,co...
Some epithelial cells can adapt to act as sensory receptors. Some examples are taste buds and the lining of the nose, eyes, and ears. Where Are Epithelial Cells Located? Epithelial tissue is composed of embryonic layers. They form from ectoderm, mesoderm, and endoderm. Since they are made up...
Type I alveolar epithelial cells are the squamous cells that form the barrier on the airway side of the alveolus, covering the vast majority of the alveolar surface. From:Encyclopedia of Tissue Engineering and Regenerative Medicine,2019 Add to Mendeley ...
The purpose of the present invention is to provide: a method for maintaining or enhancing the activity of a cell mass separated from an epithelial tissue; a method for increasing the proliferation ability of cells in an epithelial tissue; a method for producing a cell mass employing these ...
The respiratory epithelium is also an example of a slowly renewing tissue1 due to its low mitotic index, which as a results from infrequent proliferation of stem/progenitor cells in this niche. In contrast, the epithelial cell turnover rate is considerably faster in other organs such as the ...
