| Research Abstract |
It was known that important factors involved in odontogenesis in mouse dental papillae disappear between the pre- and post-natal stages of development. We examined unknown genes had down-regulated expression after birth by genome microarray analysis. The number of up-regulated genes showing an over 2-fold change decreased with time. On the other hand, the number of down-regulated genes was highest between pre- and post-natal (3,130 genes). Those were included 1,038 unknown genes, and it was recognized 16 genes, had significant reduction (fold value >10). These result suggest those down-regulated unknown genes were important factors in normal odontogenesis in dental papillae.
