Stages of embryonic development of the zebrafish
A series of stages for development of the embryo of the zebrafish, Danio (Brachydanio) rerio is described, providing for flexibility and continued evolution of the staging series as the authors learn more about development in this species. Expand
The zebrafish midblastula transition.
During the several cycles after the MBT begins, cycle length is correlated with the reciprocal of the blastomere volume, suggesting a continuation of cell cycle regulation by the nucleocytoplasmic ratio during an interval that the authors term the 'MBT period'. Expand
Origin and organization of the zebrafish fate map.
We have analyzed lineages of cells labeled by intracellular injection of tracer dye during early zebrafish development to learn when cells become allocated to particular fates during development, andExpand
Organization of hindbrain segments in the zebrafish embryo
A cryptic simplicity underlies the eventual complex structure that develops from this region of the CNS, which contains the first basal plate neurons to develop and the first neuropil. Expand
A homeobox gene essential for zebrafish notochord development
It is shown that floating head is the zebrafish homologue of Xnot, a homeobox gene expressed in the amphibian organizer and notochord, and it is proposed that flh regulates notochords precursor cell fate. Expand
Two endothelin 1 effectors, hand2 and bapx1, pattern ventral pharyngeal cartilage and the jaw joint
Together the results reveal two critical edn1 effectors that pattern the vertebrate jaw: hand2 specifies ventral pharyngeal cartilage of the lower jaw and bapx1 specifies the jaw joint. Expand
A pair of Sox: distinct and overlapping functions of zebrafish sox9 co-orthologs in craniofacial and pectoral fin development
Analysis of mutant phenotypes strongly supports the interpretation that ancestral gene functions partitioned spatially and temporally between Sox9 co-orthologs, and shows that sox9 helps regulate other early crest genes, including foxd3, sox10, snai1b and crestin. Expand
Cell movements during epiboly and gastrulation in zebrafish.
Epiboly, involution and convergent extension in zebrafish involve the same kinds of cellular rearrangements as in amphibians, and they occur during comparable stages of embryogenesis. Expand
Induction of muscle pioneers and floor plate is distinguished by the zebrafish no tail mutation
Examination of induction and patterning in a zebrafish mutant, no tail, that lacks a derivative of dorsal mesoderm, the notochord, suggests cells derived from dorsal Mesoderm may have multiple signaling functions during zebra fish embryogenesis. Expand
FGF3 and FGF8 mediate a rhombomere 4 signaling activity in the zebrafish hindbrain.
It is shown that rhombomere 4 (r4) functions as an early-differentiating signaling center in the zebrafish hindbrain and a crucial role for FGF-mediated inter-rhombomeres signaling in promoting early hindbrain patterning is demonstrated. Expand
