Feeling Their Way: How Migrating Cell Clusters Choose a Path

Migrating embryonic cell groups sprout “fingers” that pull the rest of the cluster through tight junctures in the developing body

A model of collective movement that makes some members more ready to move than others helps explain how cells migrate in the body

Sub-lethal levels of a “self-destruct” enzyme hold cells in place

Cytoskeletal fibers (green) and adhesion sites (orange) grow when the Arp2/3 complex is present in its hybrid version (right) compared with the regular, seven-subunit version (left). When Arp2/3 is absent altogether, the fibers and the adhesion sites deteriorate (center)

A seven-unit structure that helps a cell move can rearrange to help anchor it in place
