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]
The apical surface of the uterine epithelial cells is covered with microvilli that are under hormonal control and vary in length and number with the oestrous cycle and during pregnancy. A hormonally dependent glycocalyx is found outside the microvilli [ 2 ] while the center of the microvilli consists of an actin filament core which is embedded ...
Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
There are three different cell types in the epithelium. Around 25% of the cells are ciliated columnar cells; around 60% are secretory cells, and the rest are peg cells thought to be a secretory cell variant. [4] The ciliated cells are most numerous in the infundibulum, and the ampulla. Estrogen increases the formation of cilia on these cells.
Polyethylene glycol. PEGylation (or pegylation) is the process of both covalent and non-covalent attachment or amalgamation of polyethylene glycol (PEG, in pharmacy called macrogol) polymer chains to molecules and macrostructures, such as a drug, therapeutic protein or vesicle, which is then described as PEGylated.
The SPC is not intended to give general advice about treatment of a condition but does state how the product is to be used for a specific treatment. It forms the basis of information for health professionals to know how to use the specific product safely and effectively. The package leaflet supplied with the product is aimed at end-users. [3]
Washington Mayor Muriel Bowser said she had a great meeting with President-elect Donald Trump at his Florida resort and voiced optimism that they would find common ground despite their past clashes.
During pregnancy, the glands and blood vessels in the endometrium further increase in size and number. Vascular spaces fuse and become interconnected, forming the placenta , which supplies oxygen and nutrition to the embryo and fetus .
