Abstract

Objective To establish a humanized doxorubicin-induced cardiomyocyte injury model by using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). Methods The human induced pluripotent stem cells were induced to differentiate into hiPSC-CMs. Then the phenotypes of hiPSC-CMs such including cell viability, calcium transients, oxidative stress and DNA damage were detected after treated with various concentrations of doxorubicin for 24 hours. Results Doxorubicin induced a decrease in cell viability of hiPSC-CMs, destroyed calcium transients, increasing oxidative stress, leading to decrease of mitochondrial membrane potential and causing DNA damage, meanwhile dexrazoxane had cardioprotective effects on hiPSC-CMs. Conclusion Doxorubicin induced cardiomyocyte injury model is successfully established with hiPSC-CMs, overcoming the limitation of difficult access to human cardiomyocytes and the different reaction to drug between species, so could to better study on the mechanism of doxorubicin-induced cardiotoxicity and drug screening.
