[The localization of primordial germ cells in Japanese quail embryos using a technic of ultraviolet irradiation].
In the Japanese quail embryo at the stage of 6 pairs of somites, ultraviolet irradiation of the extraembryonic crescent-shaped area anterior to the level of the first somites does not lead to total sterilization of the developing gonads. There are always subsisting primordial germ cells which apparently can restore the population of gonocytes. On the contrary, complete sterilization can be obtained by irradiating the area extending posteriorly to the level of the Hensen node.
