Figure 6From: Selective segregation of DNA strands persists in long label retaining mammary cells during pregnancyPeriductal LRC do not have nuclear hormone receptors. Sections from all experimental groups were stained for the nuclear hormone receptors (a) ER-α, (b) PR, or (c) AR (green). Arrows indicate that periductal LRC (red, 5BrdU) are not double positive for the receptors. Scale bars = 10 μm. AR, adrogen receptor; 5BrdU, 5-bromodeoxyuridine; ER, estrogen receptor; LRC, label-retaining cell; PR, progesterone receptor.Back to article page
