The particular stem cells that will eventually make the future body, the embryonic stem cells (ESCs) cluster together inside the embryo towards one end: this stage of development is known as the blastocyst. (cam.ac.uk)
The other two types of stem cell in the blastocyst are the extra-embryonic trophoblast stem cells (TSCs), which will form the placenta, and primitive endoderm stem cells that will form the so-called yolk sac, ensuring that the foetus's organs develop properly and providing essential nutrients.

Researchers have generated 3D blastocyst-like structures from stem cells. (sciencedaily.com)
An international collaboration of researchers from the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan and Gladstone Institutes in the USA have generated 3D blastocyst-like structures from stem cells. (sciencedaily.com)
Published in the journal Stem Cell Reports , the study shows that the blastocyst-like structures very closely resemble actual blastocysts, and even induce proper changes in the uterus after being implanted in pseudo-pregnant mice. (sciencedaily.com)
After many more cell divisions, the embryo turns into a blastocyst that is implanted in the womb where it differentiates and grows into a fetus. (sciencedaily.com)
When they examined small clusters of cells a few days before they matured into the blastocyst-like structures, they found that the cells contained gene expression for totipotency that are found in two-cell embryos. (sciencedaily.com)
A further test comparing the blastocyst-like structures with their precursors showed that cells in the matured structures were bound close together--a hallmark of blastocyst formation and polarization that is the result of a process called compaction. (sciencedaily.com)
For instance, Science University and Oregon Health are engaged in developing blastocyst staged embryos of around 150 cells in order to provide hESC source. (grandviewresearch.com)
