Movie 3

A time-lapse movie showing the migration and the filopodial activity of EPCs visualized in Eme>lifeAct-GFP embryo. During the heart closure EPCs appear interconnected and arranged in the bilateral rows. Notice filopodial and lamelipodial activity and the formation of an actin cable that link the compacted OHC EPCs. The WH EPCs migrate collectively and stay interconnected among them. The heart proper associated EPCs appear highly enriched in actin and form a network of cells.
