Movie 7.

Real-time imaging of mitochondria in a control PLLn at 48 hpf. A 48 hpf control embryo expressing GFP in mitochondria after mito-gfp mRNA injection; the embryo was imaged every 120 milliseconds for several minutes by confocal microscopy. Lateral view; anterior to the left and dorsal to the top. This video represents 18 seconds of realtime continuous imaging. White arrow highlights an anterograde moving mitochondria while yellow arrow highlights a retrograde moving mitochondria.
