| At the end of gastrulation, the epidermis only covers the dorsal region and the ventral region is bare. |
|
| At gastrulation, the germ plasm is located in cells in the floor of the blastocoel cavity, among the cells that give rise to the endoderm. |
|
| In amphibians, there is convergent extension of the future neural plate during gastrulation. |
|
| Cell shape change is fundamental to diverse processes including gastrulation, neuronal pathfinding, immune response, metastasis, and cytokinesis. |
|
| Special focus has been on the pattern of early cleavage, blastoderm and germinal disc development and gastrulation. |
|
| The fate maps of the different vertebrates are thus similar when one looks at the relationship between the germ layers and the site of ingression of cells at gastrulation. |
|
| During gastrulation, animals form a structure called the blastopore, which is where migrating tissues tuck themselves inward to establish the three germ layers of the embryo. |
|
| During gastrulation the material of the notochord comes to lie middorsally in the roof of the archenteron. |
|
| Covered with cilia, the sea-urchin blastula swims in the water and proceeds with gastrulation. |
|
| Using explanted tissues from embryos of different ages, it has been shown that mesoderm induction is almost complete by the time gastrulation starts. |
|
| After the blastula develops, it undergoes transition to the gastrula, a process called gastrulation. |
|
| Critical periods for alcohol teratogenesis in mice, with special reference to the gastrulation stage of embryogenesis. |
|
| In amphibians, cytoplasm at the vegetal pole, rich in ribonucleic acids, becomes incorporated into a number of cells, which, during cleavage and gastrulation, lie among the yolky endoderm cells. |
|
| In higher vertebrates, in which gastrulation occurs through the medium of a primitive streak, the anterior end of the streak and the Hensen's node have properties similar to those of a primary organizer. |
|
| We are now studying other mechanisms by which mechanical cues from gastrulation might activate master genes protein product that control active multi-cellular morphogenetic movements and the formation of primitive organs. |
|
| Following gastrulation, the Medaka undergoes neurulation and organogenesis. |
|
| Fertilized groundling and sturgeon eggs were irradiated at stages from fertilization to middle gastrulation. |
|
| Somite formation begins around the third week when the embryo begins gastrulation and continues until around 52 somites are formed. |
|
| Fgfr1 null mutant embryos die during gastrulation and segmentation, while homozygous embryos of Fgfr2 knockout die before gonad formation. |
|
| Drastic expression change of transposon-derived piRNA-like RNAs and microRNAs in early stages of chicken embryos implies a role in gastrulation. |
|
|
|
| Important developmental processes observed included cleavage, formation of a blastula, epiboly, gastrulation, neurulation, organogenesis, and hatching. |
|
| A role for DNA methylation in gastrulation and somite patterning. |
|
| During gastrulation, the embryo folds inwards into a cup-like shape, forming the primary germ layers that give rise to all the organs in the body. |
|
| Gastrulation in its broadest sense is the reorganization of the cells of the blastula to form a multilayered embryo, the gastrula. |
|
| Gastrulation begins dorsally with involution of deep blastoderm cells to form an outer epiblast and inner hypoblast. |
|
| Gastrulation is the process whereby the bilaminar embryonic disk is converted into a trilaminar disk, which occurs in the third gestational week. |
