PY - 2008 DA - 2008/10/24 TI - Selective segregation of DNA strands persists in long label retaining mammary cells during pregnancy JO - Breast Cancer Research SP - R90 VL - 10 IS - 5 AB - During pregnancy the mammary epithelial compartment undergoes extreme proliferation and differentiation, facilitated by stem/progenitor cells. Mouse mammary epithelium in nonpregnant mice contains long label-retaining epithelial cells (LREC) that divide asymmetrically and retain their template DNA strands. The role of LREC during alveogenesis has not been determined. SN - 1465-542X UR - https://doi.org/10.1186/bcr2188 DO - 10.1186/bcr2188 ID - Booth2008 ER -
