Fig 2. Expression patterns of Dlx3 and EMP genes at the mRNA level during amelogenesis.

Fig 2

Real-time RT-PCR was used to analyze the expression levels of Dlx3 and EMP genes using RNA extracted from tooth germs at the indicated stages. The expression level at PN1 was set at 1, and the fold-changes at other stages were calculated relative to PN1. The data represent three independent experiments, and are shown as mean ± SD. *P <0.05 vs. the control (PN1 group).
