Prdm1a directly activates foxd3 and tfap2a during zebrafish neural crest specification.
The neural crest comprises multipotent precursor cells that are induced at the neural plate border by a series of complex signaling and genetic interactions. Several transcription factors, termed neural crest specifiers, are necessary for early neural crest development; however, the nature of their interactions and regulation is not well understood. Here, we have established that the PR/SET dom...
متن کاملZebrafish foxd3 is selectively required for neural crest specification, migration and survival.
The vertebrate neural crest is a pluripotent cell population that generates a large variety of cell types, including peripheral neurons, cartilage and pigment cells. Mechanisms that control the patterning of the neural crest toward specific cell fates remain only partially understood. Zebrafish homozygous for the sympathetic mutation 1 (sym1) have defects in a subset of neural crest derivatives...
متن کاملFoxd3 controls melanophore specification in the zebrafish neural crest by regulation of Mitf.
We describe a mechanistic model whereby Foxd3, a forkhead transcription factor, prevents neural crest-derived precursors from acquiring a melanophore fate. Foxd3 regulates this fate choice by repressing the mitfa promoter in a subset of neural crest cells. mitfa is only expressed in a Foxd3-negative subset of neural crest cells, and foxd3 mutants show an increase in the spatial domain of mitfa ...
متن کاملGenetic ablation of neural crest cell diversification.
The neural crest generates multiple cell types during embryogenesis but the mechanisms regulating neural crest cell diversification are incompletely understood. Previous studies using mutant zebrafish indicated that foxd3 and tfap2a function early and differentially in the development of neural crest sublineages. Here, we show that the simultaneous loss of foxd3 and tfap2a function in zebrafish...
متن کاملNeural crest survival and differentiation in zebrafish depends on mont blanc/tfap2a gene function.
Neural crest progenitor cells are the main contributors to craniofacial cartilage and connective tissue of the vertebrate head. These progenitor cells also give rise to the pigment, neuronal and glial cell lineages. To study the molecular basis of neural crest differentiation, we have cloned the gene disrupted in the mont blanc (mob(m610)) mutation, which affects all neural crest derivatives. U...
