Human iPSC-derived Cardiomyocytes


Human iPSC-derived Cardiomyocytes

Cardiomyocytes are cardiac muscle cells. They are terminally differentiated and facilitate contractile forces (“beatings”) of the heart. Grown in vitro as a monolayer sheath, cardiomyocytes are connected by gap junction proteins that help synchronize contraction-relaxation cycles of the cardiomyocytes. Cardiomyocytes may be used in various in vitro or in vivo studies; transplantation into normal or diseased systems; cardiac toxicology studies; or cardiovascular developmental studies. Cardiomyocytes have a high mitochondrial density, which allows them to produce adenosine triphosphate (ATP) quickly, making them highly resistant to fatigue.

Tempo-iCardio™ cells are reprogrammed from human iPSC-derived multipotent progenitor cells, using integration-free induced pluripotent stem cell (iPSC) lines under a fully defined proprietary serum-free, virus-free, genetic-vector–free, and integration-free conditions. They are cultured as monolayers and are alive for >4 weeks under defined cell culture conditions. Tempo-iCardio™ express biomarkers (q/RT-PCR gene expression analysis): ACTC1, CSPR3, KCNQ1, MYBPC3, MYH7, MYL2, PKP2, PRKAG2, TNNI3, TNNT, TPMI, TTN. Tempo-iCardio™ biomarkers (immunocytochemistry analysis): TNNT2, E-Cadherin.
