An embryonic germ cell is a type of stem cell which is pluripotent and is found in the gonads of the fetus. These germ cells are derived from the PGCs (primordial germ cells) that are found in the gonads of a fetus. The other type of cells is embryonic stem cells which are thought to be derived from the inner cell mass of a blastocyte which exists during the early developmental stage of an embryo.
These germ cells have a number of characteristics common with embryonic stem cells. It is studied that the PGCs develop into the stem cells and these cells are then responsible for giving rise to reproductive gametes i.e. ovum and sperms.
