Fig. 3. mil is required for the stabilisation of cellular processes towards the direction of migration. The orientation and length of lamellipodia-like cellular processes of leading edge cells in a WT embryo (A), slb embryo (B) and slb embryo injected with 4.3 ng mil-MO (C). The morphology of a cell from each group is highlighted in the insets. The length of the long axis of cells and their orientation with respect to the direction of movement (y-axis) were calculated and plotted, and the angle from the y-axis was calculated as cosine. Statistically significant difference is indicated (^##P<0.005).
