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]
Percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube (PEG tube) is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation).
The ciliated cells are most numerous in the infundibulum, and the ampulla. Estrogen increases the formation of cilia on these cells. Peg cells are shorter, have surface microvilli, and are located between the other epithelial cells. [6] The presence of immune cells in the mucosa has also been reported with the main type being CD8 + T-cells.
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 .
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]
Microfold cells (commonly referred to as M cells) sample antigens from the lumen and deliver them to the lymphoid tissue associated with the mucosa (MALT). In the small intestine, M cells are associated with Peyer's patches. Cup cells are a distinct cell type that produces vimentin. [13] Tuft cells play a part in the immune response. [13]

Giant cell epulis, also known as peripheral giant cell granuloma, are like fibrous epulis and occur at the anterior interdental margin, the gum between the teeth at the front. They are more common in women. They are often soft round and deep red to purplish blue. It is important they are investigated to make are they are not true giant cell ...
