Oocyte nuclear structures were studied for the scorpionfly Panorpa communis at different stages of oocyte growth, from pachytene to the first meiotic division. Using immunofluorescent and immunogold microscopy, we analyzed the nuclear distribution of RNA polymerase II, splicing factors and coilin. These factors were revealed in close association with perichromatin fibrils and, later, with some elements of the karyosphere and extrachromosomal nuclear bodies (NBs). Besides, it was shown that… CONTINUE READING
