 Primordial Germ Cells (PGCs) are unipotent precursors of the gametes. PGCs can give rise to a type of pluripotent stem cells in vitro that are called embryonic germ (EG) cells. PGCs can also acquire such pluripotency in vivo and generate teratomas. Under specific culture conditions, PGCs can be reprogrammed to embryonic germ cells which are capable of expression of key pluripotency marker...
