Table 2 Proliferation rates of normal mammary epithelial (HME1) and metastatic breast adenocarcinoma (MDA-MB-231) cells under mono- and co-culture conditions.

From: Transcriptional regulation by normal epithelium of premalignant to malignant progression in Barrett’s esophagus

  1. The mean of rates were calculated as a ratio of the cell count at 96 vs. 24 hours of culture. “Ratio” represents a fold change in the cell proliferation rate of cells under mono- over co-culture conditions. The metastatic cells proliferated markedly faster in co-culture, the normal cells showed a slight, but statistically not significant increase in proliferation. The p-values were obtained using the student’s t-test.
