Ovule development began in August, and rectangle megasporocyte began to occur in December, and linear tetrads of megaspores were formed in meiosis. In most occasions, only the chalazal megaspore was functional.

云南红豆杉胚珠从8月开始发生，大孢子母细胞12月开始发生，呈方形，减数分裂后形成4个"一"字形大孢子，在大多数情况下，只有靠合点端的大孢子发育为功能大孢子。

In first stage,from the beginning of pollination to megaspore tetrad,pollen tubes grow axially,passing through gynostemium to the ovary and from proximal placenta along ovary wall develop upward.

花粉在柱头上萌发和生长后，花粉管沿着花柱一直延伸到子房，进入胚囊释放精细胞，实现精卵结合，这就是亲和受精过程[1]。

An immunohistochemistry method and image analysis were employed to explore the expression of Caspase3 in the neuroepithelial and mesenchyme cells of each embryo.

用免疫组织化学法和图像分析技术对各组鼠胚的神经上皮和周围间充质细胞凋亡相关蛋白Caspase3的表达进行定性、定位和半定量观察。

Mesenchymal stem cells are multipotent stem cell, which can differentiate to the cells derived of mesoderm.

间充质干细胞是一类具有多能性的干细胞，在适宜条件下可以向多种中胚层来源的组织细胞分化。

Peg3 showed completely unmethylated in two cell embryos, and was strongly de novo methylated in morula stages.

结果显示，在正常发育胚胎中，Peg3甲基化印迹在小鼠2细胞胚胎之前就已经被擦除，直到桑椹胚时才被重新建立起来。

At the same time, a fertilized ovum to the uterine cavity gradually moving ,3-4 days after the arrival of intrauterine growth when cells become more than an entity, shaped like mulberry, so called morula.

与此同时，受精卵逐渐向宫腔方向移动，3—4天后到达宫腔时已发育成为一个具有多个细胞的实体，形状象桑椹，所以称为桑椹胚。
