Fig. 3
Live/dead control experimental design. (a) A549 cells labelled with CM-DiI were injected into the yolk sac of wild-type zebrafish embryos at 48 h post-fertilization and in vivo imaging was performed 5 days later. (b,c) Higher magnification images of the CHT area, where CM-DiI signal was detected despite cells being treated with toxic doses of PFA or ionizing radiation prior to injection. This level and type of CM-DiI signal therefore cannot be used to quantify micrometastasis formation. Scale bars, 100 µm.
