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.
Every other cell type in the mammalian body, apart from the sperm and ova, the cells from which they are made (gametocytes) and undifferentiated stem cells, is a somatic cell; internal organs skin, bones, blood and connective tissue are all made up of somatic cells.
