Movie S9.

Non-mutual CIL of spindle shaped cell and daughter cell post division on suspended fibers (500 nm diameter). A slow-moving spindle shaped cell (white arrow) and a fast-moving daughter spindle shaped cell (black arrow) on suspended fibers approach each other, and following contact, the non-dividing cell on right repolarizes. Subsequently both cells move together resulting in non-mutual CIL. Time shown in hours:minutes:seconds:thousandths
