Figure 6:

Shown are Ca2+ alternans (ALT) measured under conditions of oxidative stress (H2O2) in hCM alone or when also co-cultured with cardiac hMSCs from a non-failing heart (nonFailing hMSC) and failing heart (Failing hMSC). All conditions include H2O2 and hCM. Example traces are shown in Panel A and summary data in Panel B. For the summary data, filled circles represent samples from device leads and empty circles are from explanted/donor hearts. For reference, hCM in the absence of H2O2 is shown. There was no significant difference between hCM and non-failing hMSCs. Otherwise, levels of significance are shown in the figure.
