| Important developmental processes observed included cleavage, formation of a blastula, epiboly, gastrulation, neurulation, organogenesis, and hatching. |
| The future ectoderm simply thins out, expands, and covers a greater surface of the embryo in a movement known as epiboly. |
| As a result of epiboly of the animal hemisphere, the upper edge of the groove is gradually pushed down until the yolky cells of the vegetal pole are covered completely. |
| Our results show that FAK has a critical role in morphogenesis and its activity is required for a specific morphogenetic movement called epiboly. |
| At midblastula, cells of the blastoderm become mobile and spread over the yolk in the process known as epiboly. |
