Significant gene expression tendencies and GO enrichment of profiles 2, 6 and 9. (A) The significant gene expression tendencies of profiles 2, 6 and 9. (B) The significant enriched GO terms in profiles 2, 6 and 9. The 77 genes in profile 2, which consistently increased in expression, closely correlated with odontogenesis. STC-GO analysis showed genes were involved in cell adhesion, odontogenesis of dentine-containing teeth, establishment or maintenance of cell polarity, cellular component movement, epithelial to mesenchymal transition, regulation of epithelial cell migration, mesenchyme development, BMP signaling pathways, tooth mineralization, positive regulation of apoptosis, enamel mineralization, positive regulation of tooth mineralization, and organ morphogenesis.
