| Research Abstract |
The aim of this study is to understand the mechanism of dynamics in somite formation in vertebrate development and uncover the principle of pattern formation by using temporal periodicity. During somite formation, the expression of several genes oscillate in the presomitic mesoderm, thereby controlling the cyclic somite segmentation. Here, we demonstrate that the period of the oscillatory gene expression and somite segmentation is fine-tuned by the strength of Notch signaling. Moreover, we show a modulator molecule of Notch signaling is essential for the robustness of the oscillatory gene expression.
