Cell type specification in the crustacean Paryhale hawaiensis
Gruppe Gerberding - Frühe Embryonalentwicklung von Parhyale hawaiensis (Dr. Matthias Gerberding)
MPI für Entwicklungsbiologie, Tübingen
SummaryAnimal embryos specify four early cell types. Determining the underlying mechanism is one central question of developmental biology. At present, it is studied how the crustacean Parhyale hawaiensis manages such developmental program at the eight-cell stage. Specification of germ cells, e.g., depends on the genes vasa and nanos, however, in a different way than in Drosophila melanogaster , demonstrating change of gene function during evolution.
