In the mouse, a transporting epithelium is established around the 8-16-cell stage through a process known as compaction where cell definition is lost and the outer cells of the embryo form tight junctions, giving rise to the blastocyst. (conditionmed.org)
The zygote formed after fertilization divides into multiple cells through a process known as binary fission (Campbell & Reece, 2005). (brainyhomeworkhelp.com)
This is followed by a process known as cavitation in which the outer cells secret fluid containing proteins into the sphere, facilitating rapid division of the cells (Forgacs & Newman, 2005). (brainyhomeworkhelp.com)

By the time they reach the uterus in approximately 3 days, the blastomeres become morula, a ball of 16 cells (after 4 mitotic divisions), and begin to form an internal cavity. (medscape.com)
The morula continues to divide and eventually forms a blastocyst, consisting of an inner cell mass (which becomes the embryo) and an outer layer (which becomes the placenta). (iasgyan.in)

During gastrulation the bacteria cells to the root somatic cells and become internalized adhere, putting the bacteria cells inside the posterior midgut pocket by embryonic stage 9. (woofahs.com)

The lateral plate mesoderm gives rise to the heart, blood vessels, and blood cells of the circulatory system, as well as to the mesodermal components of the limbs. (wikipedia.org)
In each side, the mesoderm remains thin, and is known as the lateral plate. (wikipedia.org)
