Scatter plot analysis. (A) The list of genes that were up-regulated 2-fold by TGF-β was superimposed on the experiment describing differences in wild type vertebrae (WT, vertebrae) and wild type IVD (WT, disc). The dots representing TGF-β genes are preferentially expressed in the IVD. (B) The list of IVD enriched genes was superimposed on the experiment describing genes in cultured sclerotome that were regulated by treatment with TGF-β. The dots representing IVD enriched genes are weighted toward being up-regulated by TGF-β. (C) The list of vertebrae enriched genes was superimposed on the experiments describing genes regulated by TGF-β. Vertebrae enriched genes were more likely to be inhibited by TGF-β.
