Human gastrulation: The embryo and its models.
Developmental Biology, 2021Technical and ethical limitations create a challenge to study early human development, especially following the first 3 weeks of development after fertilization, when the fundamental aspects of the body plan are established through the process called ...

The primitive streak and cellular principles of building an amniote body through gastrulation
Science, 2021Description The nonconserved primitive streak In human development, a linear structure called the primitive streak appears 14 days after fertilization. This structure marks the transition of the embryo from having radial to bilateral symmetry.

At gastrulation, a single layer of cells is converted into an outer ectodermal covering, an inner ectodermal tube, and in triploblastic phyla, a middle mesodermal layer. This morphogenesis is driven by motility and directed by cell interactions, some of which involve adhesion and others that involve information transfer.

Comparative analysis of human and mouse development: From zygote to pre-gastrulation.
Current Topics in Developmental Biology, 2020Development of the mammalian embryo begins with formation of the totipotent zygote during fertilization. This initial cell is able to give rise to every embryonic tissue of the developing organism as well as all extra-embryonic lineages, such as the ...

Signaling regulation during gastrulation: Insights from mouse embryos and in vitro systems.
Current Topics in Developmental Biology, 2020Gastrulation is the process whereby cells exit pluripotency and concomitantly acquire and pattern distinct cell fates. This is driven by the convergence of WNT, BMP, Nodal and FGF signals, which are tightly spatially and temporally controlled, resulting ...

Our understanding of the mechanisms that control gastrulation is still in its infancy. One problem is that gastrulation is a complex set of coordinated behaviours involving directional cell movements, several types of cell interactions, changes in cell fate and gene expression.

Zebrafish gastrulation: Putting fate in motion.
Current Topics in Developmental Biology, 2020Gastrulation entails specification and formation of three embryonic germ layers-ectoderm, mesoderm and endoderm-thereby establishing the basis for the future body plan.

The evolution of vertebrate gastrulation
Development, 1994ABSTRACT The availability of molecular markers now permits the analysis of the common elements of vertebrate gastrulation. While gastrulation appears to be very diverse in the verte brates, by analyzing a head-organizer marker, goosecoid, and a marker common to all forming mesoderm, Brachyury, we attempt to identify homologous structures

Gastrulation and the Evolution of Development
Development, 1992ABSTRACT The original eukaryotic cell may have possessed the key processes necessary for metazoan development -cell differentiation, patterning and motility - and these are present in the cell cycle. Protozoa also possess key patterning processes.

Abstract The three germ layers in Drosophila are established by both the invagination of the ventral furrow, which internalizes the anterior midgut and mesoderm primordia, and the invagination of the posterior midgut primordium. The invaginations of these primordia occur by similar cell shape changes.
