Progress in Fish Primordial Germ Cells

Fish primordial germ cells(PGCs) participate in the formation of gonad,expose the mechanism of go nad differentiation. By researching PGCs can control fish sex. That is very important in the production of animal raising. Many scholars of different countries in few decads have been doing jobs on the characters, origin, migration and gonad differentiation of fish PGCs . Summarized these data are to offer the references to fish production and study.
