morula

Objective To compare the survival and developmental potential of mouse morula, early blastocysts and blastocysts cryopreserved by vitrification.

目的比较玻璃化法冻融小鼠桑葚胚期、囊胚早期和囊胚期胚胎后，胚胎存活及继续发育的能力。

the growth of a zygote into a morula is called fragmentation.

受精卵发育成桑椹胚的过程叫卵裂。

four new records of morula from china coast (gastropoda, muricidae)

中国海结螺属四新纪录（腹足纲，骨螺科）

This experiment collected 109 embryos to observe their developmental ability by ES cells microinjection into 8-16 cell stage morula or blastocyst.

本试验先后将109枚胚胎用于此项研究，通过将小鼠ES细胞注入8-16细胞桑椹胚和囊胚，观察两个不同时期注射胚胎的发育能力。

The growth a zygote a morula is called fragmentation.

受精卵发育成桑椹胚的过程叫卵裂.

rate of adherent blastocyst (75%) and rate of adherent dense morula (62. 5%) is relatively high;

囊胚的贴壁率（75%）和致密桑葚胚的贴壁率（62.5%）相对较高；

m+b: morula and blastocyst.

桑椹胚和囊胚期。

In vitro cultured early embryos, Tb4 mRNA began to increase from the zygotes stage, until the morula and blastula stages, the expression reached a peak.

在早期胚胎体外培养的过程中，Tb4mRNA从合子时期开始出现上调性表达，直到桑椹胚和囊胚，其表达量达到峰值。
