The results showed that after 2 h of culture in MEM the chromosomes of oocyte were seperated to form telophase I while a small spindle was observed around chromosomes of primary spermatocyte. However, two clear spindles were observed in the oocytes cultured in CB containing MEM. After further culture, the chromosomes of both primary spermatocyte and oocyte intermingled and formed one large spindle.

在无CB的培养液中培养的卵母细胞培养2小时后，卵母细胞已经进入第一次减数分裂的后期，染色体开始被拉向两极，而精母细胞的MI纺锤体才刚刚形成，虽然继续培养两者染色体可以合二为一并形成一个纺锤体，但是有些染色体发生滞后；当卵母细胞在含有CB的培养液中培养2小时后，在卵母细胞内形成两个相似大小的MI纺锤体，进一步培养形成一个大的纺锤体，染色体正常。
