Cardiac Toxicity Assessment Using Stem Cell Derived Cardiomyocytes



March 2, 2016

  • Cardiac toxicity is a major hurdle in drug development. In this webinar Dr. Matthew F. Peters of AstraZeneca Pharmaceuticals (Boston, MA) discusses the utility of combining ACEA Bioscience’s xCELLigence® Cardio system with stem cell-derived cardiomyocytes for evaluating the cardiac risk of compounds. The xCELLigence® Cardio system is shown to provide a high throughput, quantitative and predictive assay that can be used early in the drug discovery process. Dr. Peters specifically addresses:

    • Advancements in cellular impedance assays
    • Drug screening applications utilizing cardiomyocyte cultures
    • Cardiosafety attrition in comparison to other disease areas

    Dr. Matthew F. Peters is a principal scientist at AstraZeneca Pharmaceuticals in Boston, MA. He has a long-standing interest in harnessing the sensitivity and versatility of label-free technology to address gaps in in vitro drug discovery screening. His initial work sought to develop assays capable of characterizing GPCR ligands with functional selectivity. More recently, he has focused on developing label-free impedance-based assays to address the dearth of early phase, high-throughput screens for cardiovascular function/toxicity. He was awarded his Ph.D. in physiology from the University of North Carolina for work developing a new model of the molecular organization of dystrophin complexes. Dr. Peters’ postdoctoral fellowship at Johns Hopkins University focused on elucidating the pathogenic mechanisms involved in Huntington’s disease.
