Movie 1.

Macrophages effectively taking up protocells at the wound site. Time-lapse confocal movie showing uptake of protocells (green dots) by wound-recruited macrophages (red cells) in a wounded Tg(mpeg1:mCherry) larva at 0.5 hours post-wounding after systemic protocell injection. Note that macrophages can take up protocells accumulated at the damaged intersegmental vessel and those that leaked from this vessel towards the wound site.
