In vivo FITC-uptake by the oocyte yolk organelles.

Silenced and vitellogenic females were injected with 2 μg of FITC and their ovaries were dissected 18 h later for observation under the stereomicroscope. Note the abnormal morphology of the endocytic-originated yolk organelles in the early vitellogenic oocytes from silenced animals (dsRpATG6) when compared to control females (dsMal). Upper panel: brightfield images. Lower panel: fluorescence images. The exposure time (in milliseconds) for the fluorescence images are indicated.
