A common feature of development in most vertebrate models is the early segregation of the germ line from the soma. For example, in Xenopus and zebrafish embryos primordial germ cells (PGCs) are specified by germ plasm that is inherited from the egg; in mice, Blimp1 expression in the epiblast mediates the commitment of cells to the germ line. How these(More)
In bilaterian animals, germ cells are specified by the inductive/regulative mode or the predetermined (germ plasm) mode. Among tetrapods, mammals and urodeles use the inductive mode, whereas birds and anurans use the predetermined mode. From histological data it has been predicted that some reptiles including turtles use the inductive mode. Examining turtle(More)
Reprogramming of somatic cells to pluripotent cells promises to transform regenerative medicine. Recently many groups have achieved direct reprogramming of somatic cells by forced expression of defined factors using multiple viral vectors. However , such induced pluripotent stem (iPS) cells contain a number of viral vector integrations, any one of which(More)
mordial germ cells (PGCs) in mice and axolotls, we propose that the deletion of Nanog in species often employed as experimental models, such as frogs and teleosts (Zebrafish; Danio rerio), has been compensated by the evolution of predetermined germ cells in these organisms. Our data highlights Nanog as a major component of the gene regulatory network that(More)
