Cooperação entre estruturas pré-cordais no desenvolvimento inicial da cartilagem trabécula no crânio dos gnatostomados
(2021)
O crânio dos vertebrados, uma das aquisições evolutivas mais recentes, é formado por duas populações de células, uma delas derivada do mesoderma e outra das células da crista neural (CN). Elementos do crânio derivados das ...
Neural crests are actively precluded from the anterior neural fold by a novel inhibitory mechanism dependent on Dickkopf1 secreted by the prechordal mesoderm
(Academic Press Inc., 2007)
It is known the interactions between the neural plate and epidermis generate neural crest (NC), but it is unknown why the NC develops only at the lateral border of the neural plate and not in the anterior fold. Using ...
Snail1a and Snail1b cooperate in the anterior migration of the axial mesendoderm in the zebrafish embryo
(COMPANY OF BIOLOGISTS LTD, 2007-08-29)
The Snail genes are implicated in processes that involve cell movement, both during embryonic development and tumour
progression. In teleosts, the vertebrate Snail1 gene is represented by two distinct genes, snail1a and ...
Foxa4 favours notochord formation by inhibiting contiguous mesodermal fates and restricts anterior neural development in Xenopus embryos
(Public Library of Science, 2014-10)
In vertebrates, the embryonic dorsal midline is a crucial signalling centre that patterns the surrounding tissues during development. Members of the FoxA subfamily of transcription factors are expressed in the structures ...
