| Outline of Final Research Achievements |
In aged oocyte, low developmental rate was reported to be associated with mitochondrial abnormal distribution. Thus using the metaphase II spindle injection (MESI) method, we investigate the relationship between the spindle and mitochondrial distribution in the murine MII oocyte. The MII spindle might be a determination factor of the mitochondrial distribution in the fresh MII ooplasm, but mitochondria were no longer redistributed in the 1-day-old ooplasm, implying that the redistribution potential of mitochondria might be related to the function of the MII oocyte.
