Figure 6: Coculturing endothelial cells, macrophages, and cardiomyocytes did not produce a successful model. The percentage of live H9c2 cells of SI and SIR-0.5 h groups in the models 1-6 when using H9c2 cells. The percentage of live H9c2 cells of SIR-0.5 h groups were not decreased compared with corresponding SI groups. Data are presented as mean ± SD (n = 3–4). *P < 0.05 compared to control group; †P < 0.05 compared to SI group with the same model. SI: Simulated ischemia; SIR: Simulated-ischemia reperfusion; NS: No significance; SD: Standard deviation.
