Cells in the pluripotent ground state can give rise to somatic cells and germ cells, and the acquisition of pluripotency is dependent on the expression of Nanog. Pluripotency is conserved in the primitive ectoderm of embryos from mammals and urodele amphibians, and here we report the isolation of a Nanog ortholog from axolotls (axNanog). axNanog does not(More)
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)
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)
The enteric nervous system (ENS) is a complex network of neurons and glia within the gut wall which originate from neural crest cells. Self-renewing, multipotential ENS progenitors have been isolated from the gut of foetal as well as adult rodents, however, the identity of the ENS progenitor and the regulation of its neurogenic potential invivo, are(More)
