Figure 2. RT-PCR products generated from tooth germ and calvaria RNA. Lanes 1 and 11 are DNA markers (bp). Lanes 2 (DSP), 4 (DPP), and 6 (DSPP) are samples from the RT-PCR products generated from tooth germ with the 35-cycle protocol. Lanes 3 (DSP), 5 (DPP), and 7 (DSPP) are samples generated from calvaria RNA with the 35-cycle procedure. Lanes 8 (DSP), 9 (DPP), and 10 (DSPP) are from calvaria RNA with the 40-cycle procedure. Please note that the band densities of lanes 8, 9, and 10 (calvaria, 40-cycle) are similar to those of lanes 2, 4, and 6 (tooth germ, 35-cycle), respectively. The data are representative of seven independent experiments.
