Table 5 Percentage of cells expressing ER-α 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

  1. The number of cells expressing ER-α 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 ER-α was then divided by the total number of cells in a field of view, and the percentage of cells expressing ER-α per field of view was obtained.
