Detection of cardiomyocyte purity and cell viability. Glu: glucose. (a) Troponin was used to identify cardiomyocytes; cardiomyocyte purity was more than 90% (20x). (b) In a 5.5 mM glucose medium, the CCK-8 test was used to measure the impact of various curcumin concentrations on cardiomyocyte activity. (c) In a 30 mM glucose medium, the CCK-8 test was used to measure the impact of various curcumin concentrations on cardiomyocyte activity. (d) Cell viability over time in cardiomyocytes under different curcumin concentrations. Values are displayed as the mean and standard deviation.
