| Outline of Final Research Achievements |
Using the cerebral cortex of embryonic and neonatal mice, microarray experiments were performed to identify the molecules whose expression levels changed before and after birth. Using in utero electroporation, loss- and gain-of-function studies were carried out, and we identified molecules that negatively regulated dendritic maturation. Furthermore, we found that the migration of immature neurons was also affected, suggesting that dendritic maturation should occur appropriate time point during development. Our results uncovered a novel regulatory mechanisms of neuronal maturation soon after birth.
