Modeling Cardiac Hypertrophy: Endothelin-1 Induction with High Content Analysis

11 Jul 2013

This Application Protocol describes how to utilize iCell Cardiomyocytes in a 5-day post-plating in vitro cellular model of cardiac hypertrophy that is induced by endothelin-1 (ET-1) and quantified via increased BNP expression using a screening-compatible 384-well assay with high content analysis.

iCell Cardiomyocytes

Cellular Dynamics International

iCell® Cardiomyocytes, human induced pluripotent stem (iPS) cell-derived cardiomyocytes, aid drug discovery and improve the predictability of drug efficacy and toxicity screens, weeding out ineffective and potentially toxic compounds early in the pharmaceutical pipeline process before significant time and resources have been invested. iCell Cardiomyocytes are a mixture of spontaneously electrically active atrial, nodal, and ventricular-like myocytes that possess typical electrophysiological characteristics and exhibit expected electrophysiological and biochemical responses upon exposure to exogenous agents. Thus, these cells are a reliable source of human cardiomyocytes suitable for use in targeted drug discovery, toxicity testing, and other life science research. iCell Cardiomyocytes are shipped as cryopreserved suspensions of dissociated cells with specifically formulated culture media for optimal cell performance. Once thawed, iCell Cardiomyocytes remain viable in culture for up to two weeks, allowing for acute and chronic studies. iCell Cardiomyocytes Benefits: Human Cells - Saves valuable time, resources, and compound. Highly Pure Cell Population - Provides cardiac-specific response to reference molecules. Homogenous and Reproducible Fully Functional Model Acute and Longer-term Testing - Remain viable in culture for up to two weeks. iPS Cell-derived iCell Cardiomyocytes Applications: Cell-based Assays - Cell viability, Apoptosis, ATP production, Oxidative stress, Mitochondrial dysfunction. Electophysiological Applications - Conventional patch clamp recording, Microelectrode assay (MEA) recording.

High-Content ScreeningHigh-content screening (HCS), also known as high-content analysis (HCA), is a high-throughput technique used in drug discovery to identify substances that alter the phenotype of cells. HCS uses fluorescent microscopic imaging and automated image analysis to investigate cellular events such as apoptosis, cell viability, GPCR activation, oxide production, neurite outgrowth, and cell signaling. Find the best fluorescent labeling reagents, cellular assays, and high-content imaging systems in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :CardiomyocytesHigh ThroughputHigh throughput experiments allow the simultaneous processing of several samples. This parallelization reduces the cost per experiment and increases reproducibility and output volume of data.High Content ImagingHigh content imaging is a method combining two or more fluorescent microscopy experiments to identify substances that alter a cell’s phenotype in a desired manner. The process is adapted to multi-well plates and both the image acquisition and analysis are automated.
