highly significantP ≤0.001
Moreover, when fold changes for Notch1 and Hes7 mRNA are plotted relative to each other for all samples analysed, there is a highly significant positive correlation ( F 1,13 =21.04; P ≤0.001), which is not the case for Dll1 and Hes7 or for Dll1 and Notch1 ( Fig. 3 F-H; data not shown).
