1. It is only after gastrulation that the organs, like limbs, liver, and eyes, begin to develop.

2. We can follow gastrulation in the early development of the sea-urchin and actually see the gut forming.

3. During gastrulation the front and back, top and bottom become evident, and the basic body plan is laid down.

4. It is during gastrulation that the cells leave the outer surface and move inside the region where they will form the gut.

5. Gastrulation is an essential event during early embryo development.

6. In addition to looking at normal gastrulation, the scientists also looked at what happens to gastrulation when mutations occur.

7. After gastrulation, the embryo consists of a three-layered, flat, oval germinal disk.

8. The gastrulation of CynoPs embryos is not interrupted by removing the bottle cells in dorsal sector.

9. Objective: To investigate twisted gastrulation protein(TSG) in human and mouse testes on mRNA level in different developmental stage.

10. In most vertebrates in which they have been intensively studied - amphibians and birds - gastrulation movements are rather complicated.

11. The rearrangement of the blastula into a three-dimensional organism with inner, middle, and outer layers occurs during gastrulation .

12. Objective:Endogenous PTEN express in primitive streak during chick embryo gastrulation and mesoderm derived structure later on including heart tubes.

13. FGF control cell migration and establishment of the anterior-posterior body axis of the neural plate during gastrulation .

14. The Caltech team observed the vast reorganization and migration of cells that occurs during gastrulation in Drosophila, the fruit fly.

15. The authors discussion the staging parameters of embryonic development, the forming of gastrulation, "ammon tail fold" and "posterior amnion tube" and the forward movement of the embryo itself.

16. It is equired for the formation of the primitive streak during mouse gastrulation .

17. The outer layer of a blastula that gives rise to the ectoderm after gastrulation.

18. RT-PCR results showed that GDF8/11 gene was expressed in new fertilized cell, early gastrulation and knife-shaped embryo[sentence dictionary], which was different from that in mammals.

19. This pushing - in of cells marks the start of gastrulation.

20. These data reveal a biological role for antifreeze proteins as two key regulators in regulating cell movements during zebrafish gastrulation and later embryogenesis.

21. The researchers used a technique called two-photon excited fluorescence imaging to get a glimpse at what goes on during gastrulation in a living embryo.
