Movie 1 - Nuclear movement during cell migration - Using a cell line stably transfected with EGFP-tubulin (to label microtubules), we observe the nucleus (dark region) moving away from the leading edge of the cell (top). More movies are available here.

Movie 2- Actin retrograde flow - By microinjecting low concentrations of Rhodamine-labelled actin, we visualize actin retrograde flow in the lamella of migrating cells by fluorescence speckle microscopy.

Movie 3 - Nuclear movement after myoblast fusion - Using phase contrast microscopy to visualize nuclei, we observe the nucleus from a mononucleated myoblast cell migrating into the center of a multinucleated myotube.
