Movie 1.

F-actin dynamics visualized using UtrCH-sfGFP in the zebrafish embryo from the 8-cell stage to the high stage. Zebrafish embryos were injected with UtrCH-sfGFP and H3K9ac Fab-Cy5. Every 90 s, fluorescence images of the 8-cell stage to the high stage were acquired using a confocal microscope. Single confocal sections of UtrCH-sfGFP signals from the 8-cell stage (1.25 hpf) to high stage (3.5 hpf) are shown.
