1. The blastocoele also allows blastomeres to move during the process of gastrulation . 2. The molecular mechanism and timing of gastrulation is different in different organisms. 3. Through the process of gastrulation , the bilaminar embryonic disc becomes trilaminar. 4. Stat3 coordinates cell movements during gastrulation and contributes to establishing planar polarity. 5. Avian gastrulation occurs as cells move though the primitive streak. 6. Mixl1 plays a role in mesoderm patterning and tissue specification at gastrulation . 7. Establishing three germ layers during gastrulation is another critical step in animal development. 8. However, gastrulation was also a target in the " Drosophila" 9. Wnt signaling pathway regulates EMT in gastrulation , cardiac valve formation and cancer. 10. Hence, primitive streak is analogous to the blastopore lip in amphibian gastrulation .
