iCell^® Neurons

iCell^® Neurons are derived from human induced pluripotent stem (iPS) cells and provide a unique in vitro system for preclinical drug discovery, neurotoxicity testing, predictive disease modeling, and basic cellular research. A better and more biologically relevant alternative to current cell models, iCell Neurons offer researchers access to commercial quantities of high quality, highly pure human neurons that possess typical phenotypic characteristics and functional of mature neurons.

Specifications Cellular Dynamics International’s iCell Neurons are a highly pure population of human neurons derived from induced pluripotent stem (iPS) cells using CDI’s proprietary differentiation and purification protocols. iCell Neurons are a mixture of post-mitotic neural subtypes, comprised primarily of GABAergic and glutamatergic neurons, with typical physiological characteristics and functions. These cells quickly assume a typical neuronal morphology with branching neurites. In addition, iCell Neurons display a stable adherent single-cell morphology and remain viable for an extended culture period (≥14 days), making them amenable to a variety of electrophysiology, neurotoxicity, and synaptic neurotransmission assays. Easy to implement and available in commercial quantities, these high quality, highly pure neurons are shipped as cryopreserved suspensions of dissociated cells with specifically formulated culture media. Once thawed, iCell Neurons remain viable for extended culture periods, allowing for acute and chronic studies. iCell Neurons, Post-thaw, Represent a Highly Pure Population of Neurons and Extensive Neurite Networks

Advantages

Human Cells	iCell Neurons are terminally differentiated from human iPS cells that provide an easily accessible and biologically relevant model system to more accurately predict the relevant in vivo human response for preclinical drug discovery, neurotoxicity testing, predictive disease modeling, and basic cellular research..

Highly Pure Cell Population	Provides neuron-specific responses to reference molecules.

Homogenous and Reproducible	iCell Neurons are available in sufficient homogenous quantities and demonstrate typical human neuron functions and responses, and are highly amenable for carrying out reproducible dose and time experiments.

Fully Functional Model	iCell Neurons exhibit standard biochemical characteristics of normal human neurons, and demonstrate utility in a variety of assays including electrophysiology, neurotoxicity, and synaptic neurotransmission assays.

Easy to Implement	Cells are shipped as cryopreserved suspensions of dissociated cells with iCell Neurons Maintenance Medium and iCell Neurons Medium Supplement, specially formulated for optimal cell performance. Simply thaw, mix and use.

Acute and Longer-term Testing	iCell Neurons remain viable in culture for at least 2 weeks, thus enabling assessment of both acute and longer-term testing.

iPS Cell-derived	iCell Neurons 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.

Applications

iCell Neurons perform well in a wide variety of including (but not limited to):

Cell-based Assays

Apoptosis
ATP production
Cell viability
Oxidative stress
Mitochondrial dysfunction
Neurite outgrowth/sprouting

Electrophysiological Applications

Conventional patch clamping
Microelectrode (MEA) recording

Figure1: iCell Neurons Show a Cytotoxicity Dose Response to Known Compounds
iCell Neurons were cultured for 7 - 14 days post-thaw and exposed to a dilution series of (A) staurosporine and (B) kainic acid. Viability (as measured using cellular ATP content) was determined using the CellTiter-Glo^® Luminescent Cell Viability Assay. (Promega Corporation)

Figure 2: iCell Neurons Exhibit Neuron-like Action Potentials
Evoked and spontaneous action potentials were recorded from an iCell Neuron (9 and 14 days, respectively) using a whole-cell patch clamp methodology. All action potentials demonstrate an overshoot of the depolarization phase above 0 mV and an undershoot of the repolarization phase below baseline before correction to steady-state.

Figure 3: iCell Neurons Respond to Ion Channel Blockers
The conventional perforated patch voltage clamp technique was used with individual iCell Neurons to record the effects of compound application. The addition of classical neuron ion channel antagonists tetrodotoxin (TTX), tetraethylammonium (TEA) and nifedipine effectively blocked (A) inward sodium, (B) outward potassium, and (C) inward calcium currents, respectively, in iCell Neurons 12 - 13 days post-thaw.
