iCell Cardiomyocytes

iCell® Cardiomyocytes

iCell CardiomyocytesCellular Dynamics introduces iCell® Cardiomyocytes, human induced pluripotent stem (iPS) cell-derived cardiomyocytes. These human cardiac cells are specifically designed to 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.

Cellular Dynamics International's iCell Cardiomyocytes are highly purified human cardiomyocytes derived from iPS cells through CDI's proprietary differentiation and purification protocols.

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.

Human Cells

Because cardiac tissue shows species-specific protein expression patterns, use of terminally differentiated human cardiomyocytes, rather than other surrogate models (cadaveric or animal cells as well as transformed immortalized cells lines), for drug discovery and toxicity testing is expected to generate results that more accurately predict the relevant in vivo human response. Therefore, use of iCell Cardiomyocytes saves valuable time, resources, and compound. iCell Cardiomyocytes are differentiated from human pluripotent stem cells, maintained in vitro, and thus provide an easily accessible and physiologically relevant model system for assessing compound effects on human cardiac cellular electrophysiology.

Highly Pure Cell Population

Provides cardiac-specific response to reference molecules.

Homogenous and Reproducible

iCell Cardiomyocytes are available in sufficient homogenous quantities and demonstrate typical human cardiomyocyte behavior and responses, and are highly amenable for carrying out reproducible dose and time experiments

Fully Functional Model

iCell Cardiomyocytes exhibit standard biochemical and electrophysiological characteristics of normal human heart cells, forming electrically connected syncytial layers that beat in synchrony, with a demonstrated utility in numerous biochemical assays and arrhythmia testing.

Easy to Implement

Cells are shipped as cryopreserved suspensions of dissociated cells with iCell Cardiomyocytes Plating Medium and iCell Cardiomyocytes Maintenance Media, specially formulated for optimal cell performance. Simply thaw and use.

Acute and Longer-term Testing

iCell Cardiomyocytes remain viable in culture for up to two weeks, thus enabling assessment of both acute and longer-term toxicity testing.

iPS Cell-derived

iCell Cardiomyocytes are differentiated from iPS cells reprogrammed from a non-embryonic terminally differentiated cell type, thus avoiding the controversial and ethical issues surrounding embryonic stem cell use.


Types of Applications

iCell Cardiomyocytes have demonstrated utility in numerous biochemical and electrophysiological assays for use in toxicology, safe pharmacology, drug discovery, and basic life science research.

Cell-based Assays

  • Cell viability
  • Apoptosis
  • ATP production
  • Oxidative stress
  • Mitochondrial dysfunction

Electrophysiological Applications

  • Conventional patch clamp recording
  • Microelectrode assay (MEA) recording

Cell-based Assay Data

Cell-based Assay Data

Figure1: Typical cardiotoxic responses
iCell cardiomyocytes were plated into 96-well plates and then treated with increasing concentrations of the listed cardiotoxic agents. The graphs illustrate the dose-response relations between the tested compound and (A) viability (ATP levels), (B) apoptosis (caspase 3/7 activity), and (C) mitochondrial dysfunction (membrane potential). iCell Cardiomyocytes demonstrated concentration dependent effects over all assays.

Electrophysiological Application Data

Cardiac action potentials are the rhythmic electrical oscillation of the cardiomyocyte membrane potential. Action potentials underlie basic cardiac function and arise through the precise activity of ion channels located in the plasma membrane. Small molecule compounds can disrupt the functionality of these ion channels, particularly the human ether a' go-go (hERG) channel, which carries the rapidly activating delayed rectifier potassium current (IKr). Cardiac ion channel dysfunction can lead to prolonged action potential duration, ventricular arrhythmias, and even sudden death. iCell Cardiomyocytes exhibit characteristics and electrophysiological responses of native human cardiac tissue. The electrical activity and controllable environmental conditions of these cardiomyocytes provide an ideal model for arrhythmia testing.

Ephys Data

Figure 2: Example Action Potential Recording and Pharmacological Responses of Isolated iCell Cardiomyocytes
Spontaneous action potentials were recorded from an iCell Cardiomyocyte using the whole-cell, current clamp technique. The upper tracing illustrates an action potential train recorded while being perfused with Tyrode's saline (basal), 10 nM of the IKr blocker E-4031, or 10 μM of the calcium channel blocker nifedipine. The lower groups of tracings illustrate (A) normal action potentials during exposure to Tyrode's saline, (B and C) prolonged action potentials and early after depolarizations (EADs) in the presence of 10 nM E-4031, (D and E) recovery following washout, and (F) the resumption of spontaneous activity following nifedipine washout.
