The influence of maternal diet –induced obesity on early embryo development.

Data expressed as mean ± SEM. The number of zygotes was determined in the morning after natural mating. Blastocysts were recovered from the uterus on day 4 after mating. The number of cells per blastocyst and their distribution between the inner cell mass and the trophectoderm were analysed in 3–5 blastocysts per mouse. Values in parentheses indicate a number of mice/group.
1In both control and in 2 out of 5 obese mothers a small number of fragmented embryos at various stages of development was recovered from the oviducts.

数据以均值±标准误（Standard Error of the Mean, SEM）表示。自然交配后次日晨起统计受精卵（zygote）数量。于交配后第4天从子宫中回收囊胚（blastocyst）。每只小鼠选取3~5个囊胚，分析单个囊胚的细胞总数，以及细胞在内细胞团（inner cell mass）与滋养层细胞（trophectoderm）中的分布情况。括号内数值为每组的小鼠数量。
1 在对照组以及5只肥胖母鼠中的2只个体中，均从输卵管内回收得到少量处于不同发育阶段的碎裂胚胎。
