title: Animal development: crowd control.
abstract: To shape a developing animal, individual cell movements must be coordinated over long distances. Two recent studies help show how this is achieved during convergence and extension of the Drosophila germ-band, where polarity within the plane of the embryonic epithelium biases junction remodeling to polarize cell intercalation.
