We describe the use of a mouse ES cell based assay to identify critical time windows for Wnt/β-catenin and BMP signal activation during cardiogenic induction. The method provides a standardized platform that reliably quantifies cardiogenic efficiency, and it is applicable to the study of other cell lineages.
