| 31. | Cerberus is an inhibitor in the TGF beta signaling pathway secreted during the gastrulation phase of the embryogenesis.
|
| 32. | With a functioning digestive tube, gastrulation is now completed and the next stage of neurulation can begin.
|
| 33. | Besides ingression, two other types of internalizing cell movements may occur during gastrulation : invagination and involution.
|
| 34. | The encoded protein has sequence similarity to short gastrulation ( Sog ) and procollagen IIA proteins in Drosophila.
|
| 35. | It showed that just before or during gastrulation, embryonic stem cells lacking HDAC1 acquired visible developmental defects.
|
| 36. | More than just axonal guidance, Ephs have been implicated in the migration of neural crest cells during gastrulation.
|
| 37. | The formation of the primitive streak, through which gastrulation occurs, is induced by Koller's sickle.
|
| 38. | In " Xenopus laevis ", Cyr61 is required for normal gastrulation and modulation of Wnt signaling.
|
| 39. | As the cells of Koller s sickle migrate during gastrulation, they form different portions of the primitive streak.
|
| 40. | During gastrulation in both invertebrates and vertebrates, apical constriction of a ring of cells leads to blastopore formation.
