MDA-MB-231-B dsRed cells localize in the CHT region in 4 dpi zebrafish embryo. The movie shows one tumour cell initiating invasion via filopodium extension in the tail fin. The area of interest is indicated. The movie has been recorded for 3 hours, with frame acquisition every minute. Time lapse has been performed with Nikon A1R confocal laser scanning microscope, using 488 and 561 lasers and a 20x lens (NA 0.75).The original research can be accessed at http://dmm.biologists.org/content/9/2...
