Table 6 Percentage of cells expressing PR 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 (%)
Intact (control) gland:Implant group Nulliparous Pregnant
Intact:NSP2 21.0:5.2 5.2:1.0
Intact:NSP3 18.2:0.6 5.8:0.0
Intact:SP3 17.8:0.0 6.8:0.8
  1. The number of cells expressing PR 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 expressing PR was then divided by the number of cells in a field of view, and the percentage of cells expressing PR per field of view was obtained.
