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.
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, and…
The zebrafish neckless mutation reveals a requirement for raldh2 in mesodermal signals that pattern the hindbrain.
A new zebrafish mutation is described, neckless, and evidence that it inactivates retinaldehyde dehydrogenase type 2, an enzyme involved in retinoic acid biosynthesis is presented, providing definitive evidence for an involvement of endogenous retinoIC acid in signalling between the paraxial mesoderm and neural tube.
Structure of the zebrafish snail1 gene and its expression in wild-type, spadetail and no tail mutant embryos.
The work presented here suggests that snail1 is involved in morphogenetic events during gastrulation, somitogenesis and development of the cephalic neural crest, and that no tail may act as a positive regulator of snail1.
Hedgehog signaling is required for cranial neural crest morphogenesis and chondrogenesis at the midline in the zebrafish skull

A novel role for Shh is suggested in the movements of neural crest cells at the midline, as well as in their differentiation into cartilage, and help to explain why both skeletal fusions and palatal clefting are associated with the loss of Hh signaling in holoprosencephalic humans.
sucker encodes a zebrafish Endothelin-1 required for ventral pharyngeal arch development.
The results support a model for dorsoventral patterning of the gnathostome pharyngeal arches in which Et-1 in the environment of the postmigratory cranial neural crest specifies the lower jaw and other ventral arch fates.
Segment and cell type lineage restrictions during pharyngeal arch development in the zebrafish embryo.
It is suggested that arch precursors may be specified as to their eventual fates before the major morphogenetic movements that form the arch primordia, as in the fashion of vertebrate rhombomeres or segmental lineage compartments in Drosophila.
Requirement for endoderm and FGF3 in ventral head skeleton formation.
It is revealed for the first time that the endoderm provides differential cues along the anteroposterior axis to control ventral head skeleton development and it is demonstrated that this function is mediated in part by Fgf3.
lockjaw encodes a zebrafish tfap2a required for early neural crest development
It is demonstrated that low is required for early steps in neural crest development and suggested that tfap2a is essential for the survival of a subset of neural crest derivatives, and Mosaic analysis demonstrated that neural crest defects in low are cell autonomous and secondarily cause disruptions in surrounding mesoderm.
Jaw and branchial arch mutants in zebrafish I: branchial arches.
The results suggest that there are sets of genes that: (1) specify neural crest cells in groups of adjacent head segments, and (2) function in common genetic pathways in a variety of tissues including the brain, pectoral fins and pigment cells as well as pharyngeal arches.
