The Zebrafish as a New Model System for Experimental Biology

Abstract

The emergence of genomics and its use in combination with high-resolution bioimaging for the study of animal development mechanisms provide scientists with information on gene sets and regulation thereof during development. This enabled the identification of the core set of transcription factors involved in the development of invertebrates and vertebrates. This approach was particularly efficient due to the widespread use of transparent embryos of zebrafish and other bony fishes in these studies. These embryos can be used as model systems for the analysis of vertebrate development, even at the level of individual cells, as the various processes of development unfold in vivo.
