Oviduct epithelial cells

These cells line the fallopian tubes (oviducts). The epithelium is simple columnar, consisting of two main cell types: ciliated cells, whose beating helps move the egg/embryo toward the uterus, and secretory (peg) cells, which secrete substances that nourish gametes and facilitate fertilization and early embryo development. Their function is hormonally regulated and critical for reproduction.
