Migratory ability of gonadal germ cells (GGCs) isolated from Ciconia boyciana and Geronticus eremita embryos into the gonad of developing chicken embryos.

We conducted experiments to evaluate the ability of gonadal germ cells (GGCs), isolated from the embryonic gonads of Ciconia boyciana or Geronticus eremita, to migrate into the gonads of developing chicken embryos. Fluorescently labeled GGCs, isolated by the PBS (-) method, were transferred into the dorsal aorta of 2-day-old chicken embryos. Five days after transfer, fluorescent GGCs were detected in the gonads of recipient embryos. Our results indicate that GGCs from Ciconia boyciana and Geronticus eremita are capable of migrating into the gonads of developing chicken embryos.
