Functional characterization of 3D neurospheres assembled using iPSC-derived neurons and astrocytes

13 Mar 2024

In this application note, Molecular Devices describes methods for assembling normal human iPSC-derived cell types, including glutamatergic neurons, GABAergic neurons, and astrocytes into 3D neurospheres for compound profiling. Neural organoids and 3D spheroids are a rapidly developing technology with great potential for understanding brain development and neuronal diseases. They provide a more advanced and biologically relevant system for basic research and high-throughput drug discovery, including compound profiling and toxicity testing.

iCell Neurons

Cellular Dynamics International

iCell® Neurons, derived from human induced pluripotent stem (iPS) cells, 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. 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. iCell® 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 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® Neurons Applications: Cell-based Assays - Cell viability, Apoptosis, ATP production, Oxidative stress, Mitochondrial dysfunction. Electophysiological Applications - Conventional patch clamp recording, Microelectrode assay (MEA) recording.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.
