| Outline of Final Research Achievements |
The purpose of this research is to clarify the role of mitochondria on craniofacial development. Tooth development is one of important issues in this field. We used mouse organ culture system to investigate the role of mitochondria fission factor, Drp1, on the tooth development. The first branchial arch of mouse was cultured under the condition of Drp1 gene knock down by siRNA. The tissue section of cultured organ showed that tooth germ developed into the cap stage irrespective of Drp1 gene knock down, suggesting no essential role of Drp1 on the early stage of tooth development. For further analysis of Drp1 function in tooth development, we plan to investigate the role of Drp1 on the late stage of tooth development, such as enamel and dentin formation.
