Inductive interactions:
Specification of the veg2 lineage compartment, the definitive vegetal plate, by signals from the micromeres
| INDUCER: | Skeletogenic micromere lineage |
| TARGET: | Macromers and their progeny - veg2 blastomers |
| STAGE: | Mid-cleavage |
| INDUCTION OUTCOME: | Normal specification of the veg2 lineages and normal formation of the vegetal plate in the embryo |
| PROOFS: | Induction of gut and secondary mesenchyme elements in chimeric recombinants (4th cleavage sceletogenic micromeres combined with mesomeres)(1), sets of micromeres transplanted to the animal poles of intact recipient embryos |
| SPECIES: | Lytechinus pictus, Strongylocentrotus purpuratus |
| COMMENTS: | One micromere contacts with one or two of veg2 blastomeres, thus they must communicate with one another |
