Cells (green) showing cytoskeleton (magenta) (IMAGE) University of Göttingen Caption “Tug of war” between cells with missing “tight junction” connections: “winner” cells contract at the sides thanks to their cytoskeleton (in magenta) and bulge upwards, while the neighbouring “loser” cells are stretched out. As a consequence, collective cell motion is obstructed and the gaps cannot be closed effectively.
