A peg cell is a non-ciliated epithelial cell within the uterine tube (oviduct or Fallopian tube). These cells are also known as an intercalated or intercalary cell. These cells represent one of 3 epithelial cell types found within the normal fallopian tube epithelium and are the most infrequent (<10% of total cells). The other two cell types include ciliated columnar and non-ciliated secretory cells. The ratio of these remaining cells is dictated by an individual's hormone status. Peg cells are thought to represent a quiescent maturational stage of the background non-ciliated secretory cells. Unlike secretory cells, these cells lack apical granules reflecting their non-functional nature.
