Guidance of primordial germ cell migration
... Following on from this work in wild-type embryos, extensive mutational analysis and the use of other genetic tools showed that PGC migration can be divided into distinct steps. In addition, several molecules required for the directed migration of PGCs were identified [7–12,13]. For example, the act ...
