Fig. 1

The behavior and fate of the oosome. Green signal produced by fluorescent in situ hybridization (FISH) against Nv-bark, white is DAPI staining of DNA. The white dashed lines mark the edges of the embryos where it is not clear. Anterior is at left, and dorsal is up in all images. a–d Pre-blastoderm stage: The oosome changes shape and position within the embryo prior blastoderm formation. e Early blastoderm stage: The oosome flattens into the bud (green) as the nuclei reach the embryonic cortex. f Mid-blastoderm stage: Several pole cells immediately form from the bud in e, and remain in a separate cluster on top of the syncytial blastoderm directly at the posterior pole. g Late blastoderm stage: The pole cells divide several times to make a complex cluster of cells. h Post-gastrulation: Primordial germ cells form clusters in the interior of the embryo. Scale bar indicates 50 μm
