The dynamic localization of Vasa during mitosis in Drosophila germline stem cells. During interphase and prophase, Vasa (green) localizes as peri-nuclear bodies in the cytoplasm (nuage). When the nuclear envelope (dark blue line) begins to break down during prometaphase, Vasa gets access to the chromosomes (red) and localizes as peri-chromosomal bodies. This continues until metaphase. At anaphase, some Vasa bodies remain near segregation chromosomes, while the other bodies are displaced in between the segregating sister chromatids. NC: nucleus, Vas: Vasa.
