Kramer et al. now show that the Slit and Robo combination is even more versatile than previously thought. Muscle cells also migrate during the early stages of muscle organization under the direction of the Slit and Robo team. The response switches from repulsive to attractive; initially repelled by Slit at the midline, muscle cells are later attracted by Slit at specific attachment sites. S. G. Kramer, T. Kidd, J. H.
