Abstract
Using femtosecond laser radiation, nucleolus-like bodies (NLBs) of mouse oocytes were locally dissected without damage to zona pellucida, cytoplasmic membrane, nuclear membrane, and nucleoplasm surrounding NLB. It was found that, after dissection of 2.7 × 10–11 cm3 of NLB material, which is approximately 5.2% of 10 μm NLB volume, the probability of germinal vesicle oocyte development to metaphase II stage of meiosis decreased 3–7 times compared to the non-treated oocytes. This result indicates that NLB material organization is significant for mouse oocyte maturation.
