Blastocyst
A 5 day blastocyst will be 0.1 to 0.2 milleters (.003 to .005 inch) typically
Blastocyst
The outer layer of the blastocyst will become the trophoblast, which later develops into the placenta. The inner cell mass of the blastocyst will give rise to the embryo and eventually the fetus.
When the embryo reaches the uterus, it is a hollow ball of about 100 cells called a blastocyst. The blastocyst is made up of an outer layer of cells that will develop into the placenta and an inner cell mass that will develop into the embryo.
Human embryonic stem cells are typically extracted from the inner cell mass of a blastocyst, a structure that forms a few days after fertilization. The blastocyst is usually donated for research purposes with informed consent from the donors. Researchers can then extract the stem cells from the inner cell mass by using techniques that dissociate the cells from the embryo.
The collection of fertilized cells that is implanted in the uterus is called a blastocyst.

The zygote begins to divide into a blastocyst around 4-5 days after fertilization. This process involves multiple cell divisions and leads to the formation of the blastocyst, which is essential for implantation into the uterine lining.
