Zebrafish are increasingly used to perform phenotypic screens to identify agents that can alter physiology in a whole organismal context. Here, we describe an automated high-content chemical screen using transgenic zebrafish embryos to identify small molecules that modulate Fibroblast Growth Factor Signaling. High content multi-well screening was further refined with a particular emphasis on automated imaging and quantification that increases sensitivity and throughput of whole organism chemical screens.
