Fig. 7. Neurone-glia interactions affect directional migration. (A) Time-lapse analysis in an Hw^49c; repo-ncGFP wing posterior margin. Ectopic glia are indicated in the upper panel by an asterisk (proximal cell) and a square (distal cell). Lower panel: a proximal cell has divided, arrows show the direction of migration. (B) Schematic drawing of the same wing after immunolabelling. The posterior margin region analysed by time-lapse (A) and immunolabelling (C) is shown in the box and contains neurones (red) and glial cells (green). (C) Anti-Repo, anti-22c10 and anti-Elav labelling performed after time-lapse. Arrowheads show neuronal cell bodies. Scale bars: 40 µm (A); 35 µm (C).
