Figure 3From: Selective segregation of DNA strands persists in long label retaining mammary cells during pregnancyPeriductal LRC are not epithelial cells. Sections from all experimental groups were stained for the epithelial markers cytokeratins (green). LRC (red, 5BrdU) in periductal or peri-acinar positions are not cytokertin positive (arrows). Scale bars = 10 μm. 5BrdU, 5-bromodeoxyuridine; LRC, label-retaining cell.Back to article page
