Characterization of the Morphology, Composition, and Activity of the Germ Plasm in Nasonia vitripennis
The specification of germ cell fate in the wasp Nasonia vitripennis relies on a maternally provided ribonucleoprotein (RNP) complex called the oosome. The oosome is an exceptionally large germ plasm complex that exhibits surprisingly dynamic behavior throughout the pre-blastoderm stage. In this …

Using Xenopus laevis to study the mechanisms governing the early germline development and the formation of vertebrate body plan
… elegans, zebrafish and Xenopus, the primordial germ cells (PGC), the precursors of the gametes, are specified through the inheritance of germ plasm. Early PGC development is regulated by the genetic program coded by unique maternal factors in the germ plasm. However, the biological functions of …

The Effects of Low Temperature on Survival of Rabbit Ova
… To hasten the wide spread dissemination of germ plasm, many commercial farmers have resorted to artificial insemination. Artificial insemination has however, only allowed for the wide spread dissemination of germ plasm from the male. If the female germ plasm could also be more easily …

Molecular mechanisms governing germ line development in zebrafish and the role of this lineage in sexual differentiation
… durch eine maternale, spezifische Form des Cytoplasmas, dem so genannten Keimplasma, unterschieden. Bei den nachfolgenden Zellteilungen verteilt sich dieses Keimplasma asymmetrisch, so dass es jeweils nur in die späteren Keimzellen und nicht in die späteren somatischen Zellen gelangt. Das …
