摘要

Human-induced pluripotent stem cell (hiPSC) technology has been applied in pathogenesis studies, drug screening, tissue engineering, and stem cell therapy, and patient-specific hiPSC-derived cardiomyocytes (hiPSC-CMs) have shown promise in disease modeling, including diabetic cardiomyopathy. High glucose (HG) treatment induces lipotoxicity in hiPSC-CMs, as evidenced by changes in cell size, beating rate, calcium handling, and lipid accumulation. Empagliflozin, an SGLT2 inhibitor, effectively mitigates the hypertrophic changes, abnormal calcium handling, and contractility impairment induced by HG. Glucose concentration influences SGLT2 expression in cardiomyocytes, highlighting its potential role in diabetic cardiomyopathy. These findings support the potential utility of hiPSC-CMs in studying diabetic cardiomyopathy and the efficacy of empagliflozin in ameliorating HG-induced cardiomyocyte dysfunction. Such research may advance developments in precision medicine and therapeutic interventions for patients with diabetic cardiomyopathy.
