Embryonic stem cell. Also called ES cells, embryonic stem cells are cells derived from the inner cell mass of developing blastocysts. An ES cell is self-renewing (can replicate itself), pluripotent (can form all cell types found in the body) and theoretically is immortal.tem cells that can give rise to all cell types that are found in an embryo, fetus, or developed organism, including the embryonic components of the trophoblast and placenta required to support development and birth.
Most scientists use the term pluripotent to describe stem cells that can give rise to cells derived from all three embryonic germ layersâ mesoderm, endoderm, and ectoderm. These three germ layers are the embryonic source of all cells of the body (see Figure 1.1.
