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.
Stem cells are derived from several sources in the body. They are found in mature body tissues, umbilical cord blood, fetal tissue, the placenta, and within embryos. Stem cells develop into tissues and organs in the body. In some cell types, such as skin tissue and brain tissue, they can also regenerate to aid in the replacement of damaged cells.
