Gastrulation is a fundamental phase of animal embryogenesis during which germ layers are specified, rearranged, and shaped into a body plan with organ rudiments. Gastrulation involves four evolutionarily conserved morphogenetic movements, each of which results in a specific morphologic transformation. During emboly, mesodermal and endodermal cells become internalized beneath the ectoderm. Epibolic movements spread and thin germ layers. Convergence movements narrow germ layers dorsoventrally… Expand
Maternal contributions to gastrulation in zebrafish.
TLDR
In zebrafish, the maternally expressed gene products not only set the stage for, but they also actively participate in gastrulation morphogenesis, a critical early morphogenetic process of animal development. Expand
Regulation of gastrulation movements by emergent cell and tissue interactions.
TLDR
Emergent tissue interactions result from - and result in - morphogen signaling, cell contacts, and mechanical forces within the gastrula, which comprise a dynamic and complex regulatory cascade that drives gastrulation morphogenesis. Expand
Zebrafish gastrulation: Putting fate in motion.
TLDR
The main signaling pathways involved in germ layer progenitor cell fate specification and segregation are summarized and discussed, specifically focusing on recent advances in understanding the interplay between mesoderm and endoderm specification and the internalization movements at the onset of zebrafish gastrulation. Expand
A dynamic intracellular distribution of Vangl2 accompanies cell polarization during zebrafish gastrulation
TLDR
It is demonstrated that the dynamic Vangl2 intracellular distribution is coordinated with and necessary for the changes in convergence and extension cell behaviors during gastrulation. Expand
Gastrulation in an annual killifish: Molecular and cellular events during germ layer formation in Austrolebias
TLDR
The unique mode of gastrulation in annual killifish demonstrates that a process so ancient and fundamental to ontogenesis can have striking morphogenetic variations nonpredicted from the sole examination of model species. Expand
Endodermal germ-layer formation through active actin-driven migration triggered by N-cadherin
TLDR
This work uses live imaging and functional approaches to reveal how the endodermal layer forms in zebrafish, leading to an original model of cell segregation by active migration away from neighboring cells, a process triggered by N-cadherin. Expand
Evolution of gastrulation in cavefish: heterochronic cell movements and maternal factors
TLDR
This work strongly suggests that maternal effect genes and developmental heterochronies occurring during gastrulation have impacted morphological brain change during cavefish evolution. Expand
Reassembling gastrulation.
TLDR
Divergent and conserved strategies leading to germ layer formation in embryos as compared to in vitro systems, their upstream molecular cascades and the role of extrinsic factors in this process are discussed. Expand
Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies
TLDR
It is demonstrated that early expression of either or both of these genes in C.riparius is sufficient to invoke mesoderm invagination similar to D.melanogaster, and the possible genetic simplicity and a measurable increase in developmental robustness might explain repeated evolution of similar transitions in animal gastrulation. Expand
PCP and Septins Compartmentalize Cortical Actomyosin to Direct Collective Cell Movement
TLDR
It is reported here that planar cell polarity (PCP) proteins control convergent extension by exploiting an evolutionarily ancient function of the septin cytoskeleton, which coordinates the specific shortening of mesenchymal cell-cell contacts, which in turn powers cell interdigitation. Expand

Conserved Patterns of Cell Movements during Vertebrate Gastrulation
TLDR
Vertebrate embryogenesis entails an exquisitely coordinated combination of cell proliferation, fate specification and movement that transforms the blastula into a multilayered embryo with head, trunk and tail rudiments. Expand
Initiation of convergence and extension movements of lateral mesoderm during zebrafish gastrulation
TLDR
Using mathematical modeling, it is demonstrated that directional preference is sufficient to account for mesoderm convergence and extension, and that, at minimum, two sources of guidance cues could orient cell paths realistically if located in the dorsal midline. Expand
Live Analysis of Endodermal Layer Formation Identifies Random Walk as a Novel Gastrulation Movement
TLDR
Results uncover random walk as a novel Nodal-induced gastrulation movement and as an efficient strategy to transform a localized cell group into a layer expanded over the embryo. Expand
PTK7 is essential for polarized cell motility and convergent extension during mouse gastrulation
TLDR
The results show for the first time the polarized cell behaviors underlying CE in the mouse, demonstrate unique aspects of these behaviors compared with those of other vertebrates, and clearly define specific roles for planar polarity and for the novel planar cell polarity gene, Ptk7, as essential regulators of mediolateral cell intercalation during mammalian CE. Expand
Cooperation of polarized cell intercalations drives convergence and extension of presomitic mesoderm during zebrafish gastrulation
TLDR
Asymmetrical localization of Prickle and Dishevelled to the opposite cell edges in zebrafish gastrula parallels their distribution in fly, and suggests that noncanonical Wnt signaling defines distinct anterior and posterior cell properties to bias cell intercalations. Expand

TLDR
The assembly of a fibronectin and laminin containing ECM in the early zebrafish embryo is described for the first time and provides a framework for uncovering the interrelationship between ECM structure and cellular processes regulating convergence and extension such as directed migration and mediolateral/radial intercalation. Expand
What mechanisms drive cell migration and cell interactions in Pleurodeles?
TLDR
It is now firmly established that mesodermal cells need to adhere to a fibrillar extracellular matrix (ECM) to undergo migration during gastrulation and the role of fibroblast growth factor (FGF) during cell interactions taking place in urodele embryos is approached. Expand
Cell shape changes during gastrulation in Drosophila.
TLDR
The shape changes and behaviour of the cells participating in this process and how mutations that change cell fate affect this behaviour are described and shown and show that some of the aspects of cell behaviour specific for ventral furrow cells are part of an autonomous differentiation programme. Expand
The amniote primitive streak is defined by epithelial cell intercalation before gastrulation
TLDR
It is proposed that the amniote primitive streak evolved from the ancestral blastopore by acquisition of an additional medio-lateral intercalation event, preceding gastrulation and acting independently of mesendoderm formation to position the primitive streak at the midline. Expand
Gastrulation in the mouse embryo: Ultrastructural and molecular aspects of germ layer morphogenesis
TLDR
To this date, genes that are expressed during mouse gastrulation mostly encode cell surface adhesion or signalling molecules, growth factors and their receptors, and putative transcriptional factors, and their precise role remains to be investigated. Expand
