A peg cell is a non-ciliated epithelial secretory cell within the uterine tube (oviduct or fallopian tube). [1] These cells represent one of three epithelial cell types found within the normal fallopian tube epithelium and only make up around 10% of the total number of cells. The other two cell types are ciliated columnar and intercalary cells. [1]
Peg laterals typically occur on both sides, [2] and have short roots. [2] Inheritance may be involved, [ 2 ] and the frequency of microdontia in the upper laterals is just under 1%. [ 1 ] The second most commonly involved tooth is the maxillary third molars, [ 3 ] and after this supernumerary teeth .
Changes indicative of disease are seen as alterations in the oral mucosa lining the mouth, which can reveal systemic conditions, such as diabetes or vitamin deficiency, or the local effects of chronic tobacco or alcohol use. [3] The oral mucosa tends to heal faster and with less scar formation compared to the skin. [4]
The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus.It has a basal layer and a functional layer: the basal layer contains stem cells which regenerate the functional layer. [1]

Tight junctions also help maintain the apicobasal polarity of cells by preventing the lateral diffusion of integral membrane proteins between the apical and lateral/basal surfaces, allowing the specialized functions of each surface (for example receptor-mediated endocytosis at the apical surface and exocytosis at the basolateral surface) to be ...
Mesothelioma: (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or ...
They produce a glycoprotein, mucin that absorbs water to form a sticky secretion called mucus. They are from 12 to 25 mm. long, and about 8 mm. broad, and each opens by three or four ducts on the under surface of the apex. The Weber's glands are an example of muciparous glands located along the tongue.
