... for posterior elongation in most arthropods, although which target genes are activated in this context remains elusive. Here, we use the short germ beetle Tribolium castaneum to investigate two Wnt and Hh signaling centers located in the head anlagen and in the growth zone of early embryos. We find that Wnt/β...

... duplication followed by divergence, from a unique gene, suggesting that Hox genes may have retained a common function. The comparison of their homeodomain sequences groups Hox proteins into Anterior, Central and Posterior classes, reflecting their expression patterns in the head, trunk and tail, respectively...

...Susan C. Chapman; Frank R. Schubert; Gary C. Schoenwolf; Andrew Lumsden Previous studies of head induction in the chick have failed to demonstrate a clear role for the hypoblast and anterior definitive endoderm (ADE) in patterning the overlying ectoderm, whereas data from both mouse and rabbit...

...Heather C. Etchevers; Christine Vincent; Nicole M. Le Douarin; Gérard F. Couly ABSTRACT Most connective tissues in the head develop from neural crest cells (NCCs), an embryonic cell population present only in vertebrates. We show that NCC-derived pericytes and smooth muscle cells are distributed...

... organizing center necessary for eye development. Here we show that, in addition, the Iro-C products are required for the specification of dorsal head structures. In mosaic animals, the removal of the Iro-C transforms the dorsal head capsule into ventral structures, namely, ptilinum, prefrons and suborbital...

...Hendrik Knoetgen; Christoph Viebahn; Michael Kessel Different types of endoderm, including primitive, definitive and mesendoderm, play a role in the induction and patterning of the vertebrate head. We have studied the formation of the anterior neural plate in chick embryos using the homeobox gene...

... the nervous system begins to form, the brain parts and neuromeres are in a consistent relationship to the somitomeres. Somitomeres first appear in the head, and the cranial somitomeres do not become somites, but disperse to contribute to the head the same cell types contributed by somites in the trunk region...
