Table 2 Percentage of cells expressing either a 5-BrdU or 3H-TdR single label per field of view found in the glands and mammary fat pads of Balb/C female mice that were either intact or implanted with immortalized, premalignant cells

From: Immortalized, premalignant epithelial cell populations contain long-lived, label-retaining cells that asymmetrically divide and retain their template DNA

  Percentage (%)
  Nulliparous Pregnant
Intact (control) gland:Implant group 5-BrdU 3 H-TdR 5-BrdU 3 H-TdR
Intact:NSP2 13.0:13.0 8.2:14.3 0.6:6.8 5.2:1.9
Intact:NSP3 23.8:19.7 3.5:2.0 0.8:3.5 2.7:8.7

  1. The number of cells labeled with either 5-BrdU or 3H-TdR was counted in three random fields of view (400× magnification). In addition, the total number of cells in three random fields of view was determined (>1000 cells total counted; 400× magnification). The total number of cells labeled with either 5-BrdU or 3H-TdR was then divided by the total number of cells in a field of view, and the percentage of cells labeled with either 5-BrdU or 3H-TdR per field of view was obtained.
