From: Selective segregation of DNA strands persists in long label retaining mammary cells during pregnancy
LRC in nonepithelial mammary cells. (a) Endothelial cells that line a blood vessel are BrdU positive (brown), and a fraction of those are in cycle, as determined by [3H]-thymidine incorporation (arrow). (b) LRC exist in a mammary nerve (brown, BrdU positive). (c) LRC in fatty stroma (brown, BrdU positive). Scale bars = 10 μm. 5BrdU, 5-bromodeoxyuridine; LRC, label-retaining cell.
