Inhibition of glycolysis slows migration. a Depicted are frames from Supplementary Movie 10, demonstrating the analysis of migration speed in the posterior Lateral Line Primordium (pLLP). A similar imaging approach was used to determine the speed of migrating cells in the zebrafish pronephros. b The small molecule 3-(3-pyri-dinyl)-1-(4-pyridinyl)-2-propen-1-one (3PO) at concentrations that had no recognizable developmental effects (20 µM) delayed pLLP migration, but did not affect pronephros cell migration. The box plots represent the median, the first and third quartile (boxed area), and 1.5× interquartile range (whiskers) (n.s., not significant; t-test). c 3PO delayed the repair of a pronephros injury determined at 6 h, but no effect was observed 24 h after the injury (Fisher’s exact test). d The glucose analog 2-deoxy-D-glucose (2-DG) at 40 µM slowed pLLP migration similar to 3PO, but had no effect on pronephros collective cell migration. The box plots represent the median, the first and third quartile (boxed area), and 1.5× interquartile range (whiskers) (n.s., not significant; t-test). e While almost all injuries were repaired 6 h after wounding of control embryos, 40 µM 2-DG reduced the number of repaired injuries to 70% and 80 µM 2-DG to 58%. At 24 h after wounding, all injuries were repaired. Full bars depict not repaired injuries, open bars repaired injuries. The graphs represent the summary of at least three independent experiments (Fisher’s exact test)
