Fig. 5. Complete cluster diagram of all human mammary epithelial cell in vitro experiments, including gene names. Each column represents a single experiment, and each row represents a single gene. Ratios of gene expression relative to human mammary epithelial cell control samples grown under standard conditions are shown. Green squares represent lower than control levels of gene expression in the experimental samples (ratios less than 1); black squares represent genes equally expressed (ratios near 1); red squares represent higher than control levels of gene expression (ratios greater than 1); gray squares indicate insufficient or missing data. The color saturation reflects the magnitude of the log/ratio (see scale at top left).
