1, Cells that are introduced into young morulae to make a chimera sometimes become commandeered as germ-line cells.

2, The growth a zygote a morula is called fragmentation.

3, Aggregation of ES Cells with Mouse Morula state Embryos .

4, There was no significant difference in morula development when cloned embryos cultured in 20% hydrosalpinx fluid media (7.3%) compared with those cultured in vivo (11.1%).

5, In this study, mouse morula and blastocysts were vitrified using Straw Method and OPS Method, after frozen for 1-6d,(http:///morula.html) embryos were thawed using DPBS contained 0.

6, In the experiment, 30 A- and B- grade morula and blastula were selected for sexing.

7, Morula is rich in nutrient components and has a high value of utilization.

8, PGM gene transcription was not found in 1-8 cell and morula embryos, so glycogenesis and glycogenolysis in these embryos were not present.

9, Results Addition of leptin to embryo culture media promoted the development from 2-cell stage embryo to morula, blastocyst and hatched blastocyst and improved the implantation rate.

10, Results showed that the pregnant rate of blastula was higher than that of morula.

11, Most embryos from natural estrous rats migrated into the uterus ahead of morula stage, while embryos from superovulated rat entered the uterus at 8-cell stage.

12, The studies were performed on the cryopreservation of mouse morula by vitrification, embryo splitting and embryo transfer (ET) .

13, The results are as follows: (1) The mitochondria in the embryos before morula stage were mostly hooded.
