Web16 mrt. 2015 · The blastocyst is a structure comprising about 300 cells that contains two main regions: the inner cell mass (ICM) and the trophoblast. The ICM is made of embryonic stem cells (ES cells), which are referred to as pluripotent. They are able to give rise to all the cells in an embryo proper, but not to extra-embryonic tissues, such as the placenta. Neural stem cells are committed to the neuronal lineages (neurons, astrocytes, and oligodendrocytes), and thus their potency is restricted. Nearly all research to date has made use of mouse embryonic stem cells (mES) or human embryonic stem cells (hES) derived from the early inner cell mass.
