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 ratio of these remaining cells is dictated by an individual's hormone status. Peg cells secrete nutrients for the egg cell.
Thought to represent a quiescent maturational stage of secretory cells.
