A quantitative analysis of mitochondrial populations during the meiotic prophase of mouse oogenesis was carried out. The mean absolute area occupied by mitochondria and the mean number of mitochondria per cell increases in a linear fashion from pachytene through dictyate. The mean area occupied by mitochondria increases at pachytene and thereafter. Both small and large aggregations of mitochondria are seen, particularly during the later stages of prophase. Vacuolated mitochondria are present from preleptotene through pachytene. Mitochondria show major dynamic changes throughout fetal mouse oogenesis, which may suggest significant functional activities yet to be elucidated.
对小鼠卵子发生减数分裂前期的线粒体群体进行了定量分析。从粗线期到核网期，线粒体占据的平均绝对面积和每个细胞中线粒体的平均数量呈线性增加。线粒体占据的平均面积在粗线期及之后增加。可见线粒体的小聚集和大聚集，尤其是在前期后期。从细线前期到粗线期都存在空泡化的线粒体。在整个胎儿期小鼠卵子发生过程中，线粒体呈现出主要的动态变化，这可能表明还有待阐明的重要功能活动。
