| Proteomic analysis of the extraembryonic tissue from cloned porcine embryos. |
| The ICM will also give rise to yet another extraembryonic tissue, the primitive endoderm, which is first visible as a cuboidal layer of cells lining the blastocoelic cavity on the fourth day of development. |
| The microvilli which secure PMCs to the hyaline layer shorten, as the cells reduce their affinity for the extraembryonic matrix. |
| Expression of the novel basic helix-loop-helix gene eHAND in neural crest derivatives and extraembryonic membranes during mouse development. |
| Subsequent cell and tissue interactions lead to the functional differentiation of all embryonic and extraembryonic tissues. |
| Smad2 signaling in extraembryonic tissues determines anterior-posterior polarity of the early mouse embryo. |
