1. These patterns of expression are established within the syncytial blastoderm . 2. Her dissertation was titled " Thyroid Forming Potencies of the Early Chick Blastoderm ." 3. These actomyosin rings invaginate to separate all nuclei for one another in the syncytial blastoderm . 4. Wingless acts on Engrailed-expressing cells to stabilize Engrailed expression after the cellular blastoderm forms. 5. By implanting a fragment of quail Koller's sickle into a chicken blastoderm , Drs. 6. Early on, 256 nuclei migrate to the perimeter of the egg, creating the syncytial blastoderm . 7. This layer forms when the cells at the vegetal pole of the blastoderm combine with the yolk cell underneath it. 8. We put it in a one-day-old chicken embryo by microinjecting it into a cavity called the blastoderm , 9. Distinct tissue areas were recognized that grew and gave rise to specific structures, including the blastoderm , or chick origin. 10. After these initial patterning events, cell membranes form around the nuclei of the syncytial blastoderm converting it to a cellular blastoderm.
