Third Week: Gastrulation [PDF]

, 1971
At the beginning of the 3rd week, an important process occurs: gastrulation, the formation of the third layer of the embryo, the mesoderm.

miRNA-17 members that target Bmpr2 influence signaling mechanisms important for embryonic stem cell differentiation in vitro and gastrulation in embryos.

Stem Cells and Development, 2015
Body axes and germ layers evolve at gastrulation, and in mammals are driven by many genes; however, what orchestrates the genetic pathways during gastrulation remains elusive.

Gastrulation und Keimblätterbildung

1921
Von Vorgangen, die sich, abgesehen von ihrer Beeinflussung durch die Menge des Dotters, bei allen Wirbeltieren in wesentlich derselben Weise abspielen, haben wir die Befruchtung und die Furchung kennen gelernt. Diese fuhrt, je nachdem sie eine totale (Amphioxus, Frosch, Saugetiere) oder partielle (Vogel, Reptilien, Selachier) ist, zur Bildung eines das

Cell migration during gastrulation

Current Opinion in Cell Biology, 2005
As the gateway to shaping the body plan, gastrulation is an important problem in developmental biology, and recent advances in cell biology have overcome some of the limitations of past approaches to learning how genes control reshaping of embryonic tissues.

Setting up for gastrulation in zebrafish

2020
Soon after fertilization the zebrafish embryo generates the pool of cells that will give rise to the germline and the three somatic germ layers of the embryo (ectoderm, mesoderm and endoderm). As the basic body plan of the vertebrate embryo emerges, evolutionarily conserved developmental signaling pathways, including Bmp, Nodal, Wnt, and Fgf, direct ...

The mechanism of gastrulation in the white sturgeon

Journal of Experimental Zoology, 1993
AbstractGastrulation in the white sturgeon, Acipenser transmontanus, involves many of the same processes as in the amphibian Xenopus laevis, but the timing and relative importance of these processes are altered so that they function appropriately in a different type of egg.

Maternal contributions to gastrulation in zebrafish

2020
Gastrulation is a critical early morphogenetic process of animal development, during which the three germ layers; mesoderm, endoderm and ectoderm, are rearranged by internalization movements. Concurrent epiboly movements spread and thin the germ layers while convergence and extension movements shape them into an anteroposteriorly elongated body with ...
