As such, renal function is reliant on the proper execution of segment patterning programs. Chemical screens that assay fluorescence in live zebrafish often rely on expensive, specialized equipment for high content screening. A unique set of properties (numerous offspring, optical transparency of embryos, amenability to genetic and chemical screens) has made them powerful vertebrate research models. During the zebrafish embryonic development, the intersegmental vessels (ISVs) are formed from the main artery, the dorsal aorta (DA), through an angiogenesis mechanism between 16–19 h postfertilization (hpf) [12] , [13] . This is particularly important for screens for chemical suppressors of an induced phenotype. The zebrafish Danio rerio has increasingly been used as a whole organism model in which to perform such functional small molecule screens. Using the zebrafish photomotor response for psychotropic drug screening. Zebrafish are increasingly used worldwide as model organisms in biomedical research for answering fundamental and applied problems in biological and health-related fields.

With a growing number of screens successfully completed, a rich interface is being created between disciplines that have historically used zebrafish (e.g., embryology and genetics) and disciplines focused on small molecules (e.g., chemistry and pharmacology). Such zebrafish screens are typically carried out by treating developing embryos with libraries of small molecules to identify compounds that elicit a specific phenotype. NLM In addition, zebrafish is suitable for chemical screens at a large scale similar to cellular assays. Since its emergence as an important model organism the molecular tools for studying zebrafish have been limited. One of the most common types of zebrafish chemical screens is a “connection screen,” where well-characterized pharmacological probes are screened to identify those that modify a biological phenomenon of interest.
