Fertilization induces endocytosis in Xenopus eggs.
Fertilization-induced endocytosis in Xenopus eggs was shown by direct visualization of fluorescent dye in semithin sections. The eggs were incubated in a medium containing 0.1% Lucifer yellow CH for 20 min before, during and after fertilization and then fixed at different times after fertilization. The eggs incubated during or immediately after fertilization contained fluorescent vesicles in the cortex. These vesicles were mainly distributed in the animal hemisphere.
