Schematic presentation of the basic mammary stem cells hierarchy: common stem cell progenitors give rise to the intermediate progenitors that terminally differentiated into luminal epithelial cells and myoepithelial cells lineages. Specific molecular marker expressions distinguish each cellular progeny. α-SMA α-smooth muscle actin, Ck cytokeratin, ER estrogen receptor, and PR progesterone receptor.
