... by the organizer. This dorsalizing signal operates throughout gastrulation, can cross a Nuclepore membrane, and is not mimicked by lithium, FGFs or activin. Anteroposterior specification also takes place during gastrulation and is probably controlled by a dominant region at the posterior end of the forming axis...

...J. M. W. Slack; D. Tannahill ABSTRACT Interest in the problem of anteroposterior specification has quickened because of our near understanding of the mechanism in Drosophila and because of the homology of Antennapedia-like homeobox gene expression patterns in Drosophila and vertebrates...
