    Fruit fly egg ooplasmic streaming

    6809

    Two fruit fly (Drosophila melanogaster) egg cells, one on each side of the central black line. The colorful swirls show the circular movement of cytoplasm—called ooplasmic streaming—that occurs in late egg cell development in wild-type (right) and mutant (left) oocytes. This image was captured using confocal microscopy.

    More information on the research that produced this image can be found in the Journal of Cell Biology paper “Ooplasmic flow cooperates with transport and anchorage in Drosophila oocyte posterior determination” by Lu et al.
    Public Note
    Internal NoteAlt text: Two half-ovals separated by a black line. The one on the left contains wavelike bands of color, while the one on the right has spiraling bands. Researcher-Provided Description: During late oogenesis, Drosophila oocyte cytoplasm undergoes circular movement called ooplasmic streaming. Posterior determinants containing the fluorescently labeled marker Staufen move with the cytoplasmic flow in different patterns in wild-type (right) and myosin-V mutant (left) oocytes. Spectrum-colored tracks represent the movement of Staufen-containing particles within a 10-minute period of time. The images were acquired on a Nikon Eclipse U2000 inverted stand with a Yokogawa CSU10 spinning disk confocal head and a 40X 1.30-N.A. lens, using Evolve EMCCD, controlled by Nikon Elements software. Dear Abbey, We have some images for you. Would you like to have a look at them? How do you want me to share them with you (TIFF files are too big for email). Best, Vladimir Gelfand
