| Outline of Final Research Achievements |
Mammalian oocyte develops as a follicle that is enclosed with somatic cells and is ovulated after maturation. However, more than 99% of follicles are arrested during folliculogenesis and its mechanism is unclear. In the present study, therefore, we investigated the mechanism of oocyte dormancy maintenance and that of oocyte activation. We first developed a method to isolate follicles which does not require enzymatic treatment of ovaries. Then, with the use of the developed method, we revealed that nuclei of oocytes in dormant primordial follicles are dominated by euchromatin structure, suggesting an association between dormancy of oocytes and their chromatin structure.
