\supplementary{Figure}\label{supp:mig:1} \textbf{Cell division using the minimum ellipse.}

We model an oriented cell division over its shortest axis. To simulate this division, we generate an ellipse that is circumscribed in the cell polygonal representation. Since the polygonal representation of the cells is generated using the Voronoi diagram, we locate parent ($S^{cell}_i$) and daughter ($S^{cell}_j$) centroids on the ellipse major axis separated by a distance $d$. Therefore, the cell will be effectively divided by the shortest ellipse axis.
