| This cell group often splits into an upper layer, the epiblast, and a lower layer, the hypoblast. |
| This process is the primitive streak, and it is formed, like the sickle, of proliferating epiblast cells. |
| We also show that 3iL hESCs have a distinct epigenetic landscape, characterized by derepression of preimplantation epiblast genes. |
| When the egg of Amphioxus is in the blastosphere stage we cannot speak of either an epiblast or hypoblast. |
| The ring around the embryonic area where the walls of the vesicle are formed of epiblast and hypoblast. |
| Teeth-enamel is formed from the epiblast, and dentine, cementum, pulp from the mesoblast. |
