ChABC treatment reduces cardiac foci formation in EB cultures.

<p>(A) Ratios of beating cardiac foci corrected for total EBs plated in 8 independent experiments, and average ratio. Elimination of endogenous CS by ChABC led to a consistent, approximately 60% reduction in the number of beating cardiac foci. (*: p<0.05). (B) Time course of cardiac foci development in EB cultures. In 4 independent experiments, ChABC treatment lead to decreased numbers of cardiac foci even at d8 and d9, the earliest time points beating foci could be detected.
