This cell is rarer than the ciliated and secretory epithelial cells of the fallopian tube epithelium and is often found intercalated between them. Peg cells are generally distributed basally along the epithelium and have been found in high concentrations at the fimbriated, distal end of the fallopian tube in humans. It may have a regenerative/stem-cell function. In humans, markers include EPCAM, CD44, and ITGA6.
