Fig.1A_Oskar mRNP dynamics during stage7-10 oocytes. (A) Model of oskar mRNA transport in stage 7 to 10 oocyte. Oskar mRNA is synthesized in the nurse cell nuclei, transported through the ring canals interconnecting the nurse cells and the oocyte, and ultimately localized to the posterior of the oocyte in a tight crescent. Oskar mRNA (red) colocalizes with Staufen protein (green) at the oocyte's posterior.
