Outline of Final Research Achievements |
In synthetic biology, synthetic gene circuits that are constructed by assembling several genetic sequences are used to control cellular behaviors as desired. A purpose of this research is to develop a method to apply this synthetic biological strategy, which is a combination of mathematical modeling and biological experiments, to construct useful gene circuits in mammalian cells. For this purpose, we tried to construct a synthetic gene circuit in which diversification ratio of cellular types are controllable based on mathematical models by assembling multiple gene circuits. Even though the gene circuit with desired functions was not realized, we could design the necessary elements for the system, inspected the validity of the system, and deepen the understanding about the future problems.

Academic Significance and Societal Importance of the Research Achievements |
合成生物学では、数値シミュレーションを用いて有用な生命システムを効率的に設計、構築するという手法が用いられる。この手法は、微生物ではすでに多くの成果が得られており方法論もある程度確立されていたが、動物細胞では難しいというのが現状であった。そこで、本研究では動物細胞に対してこうした手法を活用するためのシステム論を確立することを目的とした。こうした動物細胞における合成生物学的手法が確立は、再生医療などへの応用につながると期待される。結果的に、本研究ではシステムの完成形の実装には至らなかったものの、必要な要素の検証やモデルの妥当性の確認を行い、今後の課題についての理解を深めることは出来たといえる。
