| Research Abstract |
The process of morphogenesis of multi-cellular organisms can be expressed as "Genes-Cells-Shape". To elucidate the detailed process based on actual substances, I studied a latter half of the process from Cells to Shape using a mathematical cell model. A computer simulation was performed of an epithelial invagination of the trachea formation of Drosophila, referring to actual observations. The simulation of the invagination was succeeded based several assumptions of cell behaviors. However, one of the assumptions, cell migration toward the embryo inside is arguable. On the other hand, I studied a polygonal cellular pattern of invagination in the neural tube formation. Here, anisotropic localization of the planar cell polarity gene, celsr was elucidated to cause anisotropic localization of myosin molecules that generates morphogenetic force. Then, one of the routes from genes to shape was established.
