We have found that the cytoplasmic organelles changed dynamically their shape during which the morphogenesis began after cell proliferation at MBT. For example at MBT, the golgi apparatus, which is necessary for protein traffic and modification, was reassembled from its fragments, and the P-body, in which mRNAs degrade efficiently, emerged. We think that these changes were necessary for protein secretion and maternal mRNA degradation after MBT. Otherwise, we showed that the molecular mechanism which triggered the initiation of cell cycle elongation at MBT.
