Movie 1

Cytoplasmic movement in a WT embryo from 20 mpf to 40 mpf. Rhodamine dye was injected at 10 mpf and embryos were imaged from 20 mpf to 40 mpf. The persistent cytoplasmic streaming that transports rhodamine to the animal pole can be visualized. 8 embryos were observed and this movie shows the representative result. A, animal pole; V, vegetal pole. Scale bar: 200 μm.
