Polyethylene glycol (PEG; / ˌ p ɒ l i ˈ ɛ θ əl ˌ iː n ˈ ɡ l aɪ ˌ k ɒ l,-ˈ ɛ θ ɪ l-,-ˌ k ɔː l /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine.
Following the initial isolation in 1958 of epithelial cells from the kidney tubule of an adult Cocker Spaniel dog by Stewart H. Madin and Norman B. Darby, Jr., [3] the cell line bearing their name was employed primarily as a model for viral infection of mammalian cells.
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]
There is evidence demonstrating PEG-induced repair of specific nerve cells in animal models: It has been shown that macrogol can improve healing of spinal injuries in dogs. [42] One of the earlier findings is that macrogol can aid in nerve repair in earthworms. [43]

Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts , osteoclasts and trophoblasts , during embryogenesis , and morphogenesis . [ 1 ]
Freezer Storage Tips. Since it extends the life of perishable items by weeks to months, “freezer storage is an amazing way to reduce food waste,” explains Gangeri.
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.
