Bi‐modal strategy of gastrulation in reptiles [PDF]
Background: Amniote gastrulation is often described with respect to human, mouse and chick development by the presence of the primitive streak, a posterior‐to‐anterior midline morphological cell ingression feature that has come to define Amniote gastrulation.

During development, a single cell is transformed into a highly complex organism through progressive cell division, specification and rearrangement. An important prerequisite for the emergence of patterns within the developing organism is to establish asymmetries at various scales, ranging from individual cells to the entire embryo, eventually giving ...

Fetal Alcohol Spectrum Disorder (FASD) arises from maternal consumption of alcohol during pregnancy affecting 2%–5% of the Western population. In Xenopus laevis studies, we showed that alcohol exposure during early gastrulation reduces retinoic acid (RA)

Gastrulation: PARtaking of the Bottle [PDF]
Gastrulation in C. elegans embryos involves ingression of individual cells, but is driven by apical constriction of the kind that promotes migration of epithelial cell sheets. Recent work shows that PAR proteins, known for their role in polarization and unequal cell division, are also associated with the polarization that establishes this apical ...

Formative pluripotent stem cells show features of epiblast cells poised for gastrulation
The pluripotency of mammalian early and late epiblast could be recapitulated by naïve embryonic stem cells (ESCs) and primed epiblast stem cells (EpiSCs), respectively.

Tunicates are a diverse group of invertebrate marine chordates that includes the larvaceans, thaliaceans, and ascidians. Because of their unique evolutionary position as the sister group of the vertebrates, tunicates are invaluable as a comparative model and hold the promise of revealing both conserved and derived features of chordate gastrulation ...

Molecular anatomy of the pre-primitive-streak chick embryo [PDF]
The early stages of development of the chick embryo, leading to primitive streak formation (the start of gastrulation), have received renewed attention recently, especially for studies of the mechanisms of large-scale cell movements and those that ...

Adhesive Crosstalk in Gastrulation [PDF]
Recent studies show that signaling through integrin receptors is required for normal cell movements during Xenopus gastrulation. Integrins function in this process by modulating the activity of cadherin adhesion molecules within tissues undergoing convergence and extension movements.

Ventral furrow formation, the first step in Drosophila gastrulation, is a well-studied example of tissue morphogenesis. Rho1 is highly active in a subset of ventral cells and is required for this morphogenetic event.
