The blastocyst has only three parts: the inner cell mass (A), the trophoblast cell layer (B), and the inner cell cavity (C). The inner cell mass is the part that in nature goes on to form the ...

sometimes called "pluripotential stem cells" (PSCs), are found in the inner cell mass of the preimplantation embryo and in certain cell populations of the early fetus. Stem-cell research took a ...

that becomes the placenta and the inner cell mass (ICM) that eventually produces the epiblast, or fetal tissue, and the hypoblast, or the yolk sac. When they tracked GFP expression, the team found ...

The blastocyst stage is characterized by the presence of a blastocyst cavity, outer cell mass and inner cell mass. Embryonic stem cells are derived from the inner cell mass of the blastocyst.

reside in the so-called inner cell mass in a few-days old embryo, called a blastocyst. During the last 25 years or so, researchers have been able to culture embryonic stem cells extracted from embryos ...

The research is published in the journal Regenerative Therapy. Through the isolation of inner cell mass from blastocyst stage embryos and culturing them, the researchers succeeded in generating ...
