Movie 1

Nuclei shrinkage under fluid shear stress. Fluorescent images of nuclei of MDCK cells subjected to shear stress (1.1 dyn/cm²), showing that the nuclear sizes decreased with flow. Nuclei visualized with Hoechst 33342. The images acquired at 2 min per frame for a total recording time of 120 min. Yellow arrow indicates the start of flow and the flow direction.
