“…Cytoskeleton-mediated processes are involved in the final stages of female gamete formation, including meiotic progression and first polar body emission [2,3]; in the process of fertilization, including second polar body emission, pronuclear formation and migration [46,61,62]; and in the process of compaction during pre-implantation embryo development [21,47]. In mammals, the organization and dynamics of cytoplasmic intermediate filaments during oocyte maturation have never been described, and there is still limited information available regarding early embryogenesis [7,12,25,43,44,52,53,60].
