The zebrafish is a powerful experimental model to investigate the genetic and morphologic basis of vertebrate development. Analysis of skeletogenesis in this fish is challenging as a result of the small size of the developing and adult zebrafish. Many of the bones of small fishes such as the zebrafish and medaka are quite thin, precluding many standard assays of bone quality and morphometrics commonly...
The ability to identify a phenotype causing mutation is essential for successful use of mutagenesis screens in many model organisms. Mapping mutations was for a long time a bottleneck in zebrafish research, as the standard method for mapping and identification of mutations was time consuming and expensive. The development of new sequencing technologies in the last couple of years has enabled the rapid...
In vertebrates, the dorso-ventral (DV) axis is defined by the combinatorial action of localised Wnt, FGF and Nodal signalling along with the antagonizing activities of Chordin and BMP pathways. Our knowledge of the factors that may act in concert with these core pathways to regulate early embryonic patterning is far from complete. Furthermore, while all three germ layers respond to these patterning...
