Time course of transforming growth factor beta (TGF-β)1-dependent changes in gene expression. The Cy3 signal is shown on the y axis and the Cy5 signal is shown on the x axis. The 0 hours graph represents the self–self hybridization for Cy-dye labeling noise control, and demonstrates a minimal level of systemic noise. TGF-β induces a progressively larger alteration of gene expression over time.
