Depletion of pericentrin in mouse oocytes disrupts microtubule organizing center function and meiotic spindle organization

Abstract excerpt

Accurate chromosome segregation is dependent on the formation and stability of the microtubule spindle apparatus. Meiotic spindle assembly in oocytes differs from the process used during mitosis, and is regulated by unique microtubule organizing centers (MTOCs) that lack centrioles. To gain insight into the molecular composition and function of acentriolar MTOCs in mouse oocytes, we assessed the role of a key...
