smalRNA seq of IPSC-cardiomyocytes treated with exosomes before hypoxic stiumli

This experiment aimed to investigate whether exosomess released by IPSC-cardiomyocytes during hypoxia can positively influence cardiac electrophysiology and miRNA expression during hypoxic stress. A multielectrode array (MEA) system was used as an in vitro method of recording real-time cardiac electrophysiological activity, highlighting the biological effects facilitated by exosomes. Additionally, miRNA-sequencing was performed to compare miRNA expressions in exosome-preconditioned and non-preconditioned IPSC-cardiomyocytes, elucidating important modulators of cardiac electrophysiology.
