Germ cell transplantation has tremendous applications in transgenic animal production, assisted reproductive technology, and
germline stem cell research. Here, we report for the first time the production of individuals from intraperitoneally transplanted
primordial germ cells (PGCs) in animals. To trace the behavior of exogenous PGCs in recipients, PGCs visualized by a green
fluorescent protein gene were used as donors. The PGCs prepared from the genital ridges of hatching embryos were transplanted
into recipients at various developmental stages. The PGCs injected into the peritoneal cavities of hatching embryos had the
ability to migrate toward, and to colonize, the genital ridges of recipient embryos. Furthermore, donor-derived PGCs proliferated
and differentiated into mature eggs and sperm in the allogenic gonads; the resulting gametes produced live fry, showing the
donor-derived phenotype, through fertilization. Combined with in vitro culture, genetic modification, and cryopreservation
of PGCs, this technique provides new approaches for fish bioengineering.
