... ectoderm mesectoderm Twist Su(H) Dorsal Comparative genome analyses have revealed remarkable constancy in the genetic composition of different animals. Vertebrates contain an average of 25,000 to 30,000 protein-coding genes, and most of these genes can be aligned with one another even among...

... domain and a 160 amino acid cytoplasmic tail. The hibris transcript is expressed in a broad range of tissues and across life stages. In the embryo, hibris transcript is present in the mesectoderm, then in a group of cells at the developing CNS midline and in a subset of glia. In the periphery, hibris...

... the specification of mesendoderm, the restriction of mesectoderm fate to P 1 descendants, and germline quiescence during embryogenesis. We suggest that SPN-4 post-transcriptionally regulates the expression of multiple developmental regulators. Such SPN-4 targets might then act more specifically to generate a subset...

...Anne Baroffio; Elisabeth Dupin; Nicole M. Le Douarin ABSTRACT The cephalic neural crest (NC) of vertebrate embryos yields a variety of cell types belonging to the neuronal, glial, melanocytic and mesectodermal lineages. Using clonal cultures of quail migrating cephalic NC cells, we demonstrated...
