Movie 2

YSL nuclei movements in wild type embryos. Embryos were injected with SYTOX Green at 1-cell stage to visualize the YSL. The injected embryos were embedded in low melting agarose to show the animal (below) and lateral (above) view and the movie was started when they, reached oblong stage. Frames were taken every 3 min. Note the changing distribution of the YSL nuclei: YSL nuclei first stay as 3 rows in the periphery of the yolk, then the nuclei aligned at one row and as doming starts some YSL nuclei migrate to the middle.
