This study was conducted to determine the specific roles of in early germ cell development and its consequences on sexual identity. In brief, we have developed transgenic knockdown (ER2-KD) and knockout (ER2-KO) medaka lines and assessed the in SDF1/CXCR4-mediated chemotactic PGC migration, and calcium homeostasis-related germ cell survival and death, which, in some cases, eventually affects the seeding? human population of germ cells in the gonadal disrupts and anlagen regular sexual advancement.
