Schematic representation of the development and migration of PGCs in mouse and chicken. a Mouse PGCs originated from epiblast, and migrate through dorsal mesentery to seettle in the genital ridge. b Chicken PGCs located at the center of area pellucida region, and they migrate through germinal crescent and vascular system to settle in the genital ridge
