Designer Embryo Numerous signaling pathways have been implicated in controlling early vertebrate embryogenesis. P.-F. Xu et al. (p. 87) identify the minimal set of factors necessary to get uncommitted cells to organize a complete embryo. Two opposing gradients of the growth factors Nodal and Bone Morphogenetic Protein were sufficient to instruct zebrafish embryonic pluripotent cells to organize a complete embryo, not only in vivo but also in vitro. These findings may provide guidance for…

Construction of a mammalian embryo model from stem cells organized by a morphogen signalling centre

Embryoids provide an in vitro model of mammalian embryo that displays extensive development of germ layer derivatives and that promises to be a powerful tool for in vitro studies and disease modelling.

Generation of Naïve Blastoderm Explants from Zebrafish Embryos.

It is demonstrated that a single signaling molecule - a Nodal ligand - is sufficient to induce germ layer formation and extension morphogenesis in otherwise naïve embryonic tissues and is anticipated to be of great utility to many zebrafish researchers.

This chapter summarizes historical perspectives as well as recent molecular and genetic advances regarding the mechanisms that regulate symmetry-breaking in the vertebrate egg and early embryo, the pathways that are activated by these events, and the role of these pathways in the formation and function of the organizer.

Zebrafish embryonic explants undergo genetically encoded self-assembly

It is shown that zebrafish embryonic tissue explants, prepared prior to germ layer induction and lacking extraembryonic tissues, can specify all germ layers and form a seemingly complete mesendoderm anlage, which suggests that z stripes do not undergo bona fide self-organization, but rather display features of genetically encoded self-assembly, where intrinsic genetic programs control the emergence of order.

A mesoderm-independent role for Nodal signaling in convergence & extension gastrulation movements

A mesoderm-independent, cell-autonomous role for Nodal signaling in neural C&E that may cooperate with previously-described mesoderman-dependent mechanisms to drive AP embryonic axis extension is revealed.

BMP gradients: A paradigm for morphogen-mediated developmental patterning

This Review lays out the current understanding of how diffusible morphogens form gradients to subdivide germ layers into distinct territories and organize body axes, regulate growth, and maintain stem cell niches in developing embryos.

Generation of Ectopic Morphogen Gradients in the Zebrafish Blastula.

A comparative study reveals that all these methods allow to generate morphogen gradient(s) that are able to induce, both in vivo and in vitro, the formation of a well-patterned embryonic axis.

Studying evolution of the primary body axis in vivo and in vitro

It is argued that embryo-like systems can be employed to inform previously uncharted aspects of animal body plan evolution as well as associated patterning rules.



Bone morphogenetic protein 4: a ventralizing factor in early Xenopus development.

It is interesting, however, that blastopore formation in such embryos can occur perfectly normally and suggests that XBMP-4-induced ventralization occurs after the onset of gastrulation.

Nodal induces ectopic goosecoid and lim1 expression and axis duplication in zebrafish.

A role for a nodal-like factor in pattern formation in zebrafish is suggested, as indicated by the appearance of a region over-expressing gsc and lim1 and isolation and expression in the shield of the lim1 gene.

Zebrafish organizer development and germ-layer formation require nodal-related signals

It is reported that the zebrafish squint (sqt) and cyclops (cyc) genes have essential, although partly redundant, functions in organizer development and also in the formation of mesoderm and endoderm.

Nodal signaling and the zebrafish organizer.

The combination of genetic, molecular and embryological approaches in zebrafish has provided a framework to understand the mechanisms underlying organizer development.

Activin- and Nodal-related factors control antero–posterior patterning of the zebrafish embryo

It is proposed that modulation of intercellular signalling by Antivin/Activin and Nodal-related factors provides a mechanism for the graded establishment of cell fates along the antero–posterior axis of the zebrafish embryo.

The molecular nature of the zebrafish tail organizer

By isochronic and heterochronic transplantation, the existence of a tail organizer deriving from the ventral margin of the zebrafish embryo is revealed, which is independent of the dorsal Spemann organizer.

A role for FGF-8 in the dorsoventral patterning of the zebrafish gastrula.

It is concluded that FGF-8 is involved in defining dorsoventral identity and is an important organizing factor responsible for specification of mesodermal and ectodermal dorsolateral territories of the zebrafish gastrula.

The entire zebrafish blastula-gastrula margin acts as an organizer dependent on the ratio of Nodal to BMP activity

Formation of the vertebrate embryo is known to depend on the activity of organizing centers. The dorsal Spemann organizer is the source of growth factor antagonists that participate in the creation
