The new GV preparation method we developed allowed the best visualization of chromatin distribution after Hoechst or CMA3 staining. Our results showed that GV chromatin configurations are different among different species, and thus, while chromatin condensed into a ring around the nucleolus in porcine and bovine oocytes, no such a ring was observed in caprine oocytes; Porcine oocytes were synchronized at GV1, goat oocytes at GV3n and bovine oocytes at GVf configurations before GVBD occurred, indicating that these configurations are progressive towards final maturation rather than atresia; Changes of chromatin configurations were associated with gene activity of transcription; GV chromatin configurations were affected by the environmental changes such as serum starvation and elevated temperature.

应用该技术对猪、山羊和牛不同大小、不同健康程度卵泡及体内和体外成熟过程中卵母细胞染色质构型的变化发现：1）不同动物卵母细胞染色质构型不同；猪和牛卵母细胞染色质围绕核仁凝集形成环，但山羊卵则没有此环。2）卵母细胞在GVBD之前都同步在某一染色质构型；猪同步在GV1，山羊GV3n，牛GVf，说明这些染色质构型代表着进行性变化。3）染色质构型的变化反映基因转录活动的变化。4）染色质构型受环境变化的影响。

Oocytes from different size of follicular had different development ability.
