Mouse Oocyte Microtubule-Associated Protein (ASPM) Expression and Subcellular Localization

Microtubule-Associated Protein (ASPM) appears to have a role in meiotic spindle assembly and meiotic progression in mouse oocytes; localized to the entire oocyte spindle at metaphase I (MI) and metaphase II (MII), colocalizing with the spindle microtubule protein acetylated tubulin (Ac-tubulin).

Legend

  • GV - germinal vesicle, large centrally located oocyte nucleus.
  • GVBD - germinal vesicle undergoing breakdown.
  • pro-MI - Prometaphase I, spindle apparatus formed, and chromosomes attached to spindle fibres by kinetochores.
  • MI - metaphase I
  • MII - metaphase II
  • Ac-tubulin - (green) microtubules
  • ASPM - (red) Microtubule-Associated Protein
  • DAPI - (blue) chromosomes.
