Movie 1. Time-lapse imaging of SM migration in concert with an endogenous FGF/egl-17 transcriptional reporter. Spinning disk confocal time-lapse showing a portion of the FGF-dependent phase of SM migration. The SM and other M lineage cells are visualized in cyan. The FGF/egl-17 transcriptional reported is depicted using the glow lookup table. Movie corresponds to Fig. S5. Animal is oriented with anterior to left and dorsal to top. Time elapsed is labeled in minutes. Scale bar = 10 mm.
