How Difficult Is Inference of Mammalian Causal Gene Regulatory Networks?

Figure 5

Scatter plots show the extent of tissue-specific differential expression in dental epithelium (y-axis) and dental mesenchyme (x-axis) as a result of Pax9 knockout (A), Msx1 knockout (B), Bmp4 stimulation (C) and Wnt stimulation (D).

Coloured points represent probes of differentially responsive genes between the two tissues. Pearson correlation is also shown.
