FIG. 5.

Influence factor ${\psi }_{\mathit{M}\mathit{i}\mathit{s}}$ of a stationary cell due to the presence of another cell as a function of the rotation angle and the cell distance. Each polar diagram represents a different cell shape (Fig. 7). Top left: sphere barely touching the substrate (h = 18 $\mu$m). Top right: hemisphere (h = 10 $\mu$m). Bottom left: high ellipsoid (h = 5 $\mu$m). Bottom right: flat ellipsoid (h = 2.5 $\mu$m). The influence on the stationary cell decreases with decreasing cell height.
