Outline of Final Research Achievements |
We have obtained a large number of findings, mainly developmental findings, as well as aging and regeneration in the primate model animal, common marmoset. In particular, through this study, we have obtained knowledge on the basic knowledge as a model animal in common marmoset cochler development, allowing comparison with rodent models and with human specimens. In the process, numerous differences between primate models and existing rodent models were identified. We believe that we have succeeded in creating a platform for research on the inner ear of a primate model animal, which was our initial goal. We believe that our study lead to more applied research such as disorder models using this animal in the future, and we have obtained results that will lead to further research.

Academic Significance and Societal Importance of the Research Achievements |
従来内耳研究ではヒト検体の利用が困難なことから、マウスモデルがよく利用されいた。しかし、しばしばマウスモデルではヒトの疾患や病態を説明できないことが存在することが知らている。今回、我々の検討では霊長類モデル動物であるコモンマーモセットに注目し、その内耳における発生から加齢までを対象に検討を行った。 検討の結果、本動物を今後の内耳研究に利用する際に必要となる基礎的な情報が集積され、本動物を用いたマウスモデルとは別の角度からの研究が可能になると考えられる。また、齧歯類と霊長類との間の種差も多数見出し、種差の点からも霊長類モデル動物の有用性が示された。本モデルは内耳研究に貢献することが期待される。
