The cytoskeleton organizes germ nuclei with divergent fates and asynchronous cycles in a common cytoplasm during oogenesis in the chordate Oikopleura.

In early meiotic nuclei, telomeres and nuclear pore complexes ”cluster in non-overlapping regions of the nuclear envelope”. During some stages of oocyte maturation, the telomeres of the endocycling nurse cells “clustered at the nuclear periphery, in a compartment with no detectable elongating RNA polymerase II”. Colchicine treatment induced early oocyte differenciation. Used rabbit polyclonal anti-histone H3 phospho-serine 10 (H3S10P) from Upstate, cat. num. 06-570.
