Inductive interactions:
veg2-to-veg2 signal
| INDUCER: | veg2 |
| TARGET: | veg2 |
| STAGE: | Mid-cleavage - mid-gastrula |
| INDUCTION OUTCOME: | promotion of endoderm gene expression within the veg2 domain |
| PROOFS: | A single micromere retained after deletion of 3 micromers after 4th cleavage were deleted suffices to endow 75-100% of veg2 progeny with the capacity to express Endo16 at a normal level and to form a normal functional vegetal plate |
| SPECIES: | Strongylocentrotus purpuratus |
| COMMENTS: | One micromere contacts with one or two of veg2 blastomeres, thus they must communicate with one another |
