Figure 1From: Embryonic cells contribute directly to the quiescent stem cell population in the adult mouse mammary glandLuminal and myoepithelial lineage marker expression during embryonic mammary gland development. (A) Schematic representation of embryonic mammary rudiment formation in the female from e11.5 to birth. Five pairs of mammary glands form in the female mouse. (B) Immunostaining for K14 (green) and Gata3 (red) (top), K14 (green) and p63 (red) (middle), and K14 (green) and K8 (red) (bottom) in WT MG at e11, e13, e15, and newborn (one day old). Scale bars, 40 μm. e, embryonic day; MG, mammary gland; WT, wild type.Back to article page
