microBrain® Assay Ready
Structure Leads to Improved Cell-Based Assay Outcomes
A Structured Environment for Cell Performance
StemoniX® microBrain® Assay Ready, pre-plated product is a human iPSC-derived, balanced culture of cortical neurons and astrocytes (nominally 50%-50%) derived from a single source that demonstrates accelerated features of cell maturity, cell functionality and cell-to-cell interaction to closely represent human brain tissue.
microBrain cortical neurons are primarily excitatory (glutamatergic) neurons balanced with inhibitory (GABAergic) neurons (approx. 80% to 20% ratio).
microBrain Assay Ready is delivered to the customer pre-plated, under ambient conditions and is an ideal model for neurotoxicity and neuro safety studies, high throughput screening and drug discovery.

Neural Network Structure & Cell Maturity
The microBrain neural network structure develops extensively and supports enhanced maturity of the neurons and astrocytes. The effectiveness of microBrain’s network structure and cell maturity level is evident by:
- Density of Functional Synapses Resulting in Active Neuronal Circuitry
- Expression of Key Neuronal Genes
- Strong Response to Neurotransmitters
MAP2 – GFAP – Nuclei
MAP2 – Synapsin – Nuclei
Gene Expression Profile Characterized in StemoniX microBrain Neural Cultures
Glutamate Dose-Response Curve 8 weeks old

Neuron & Astrocyte Advantages
The relationship between neurons and astrocytes is well documented in literature and the benefits are now available in a pre-plated format via StemoniX microBrain Assay Ready products. Astrocytes are known to support, protect and enhance the development of neurons. microBrain’s neurons have a fully developed foundation of astrocytes that have been derived from a single source resulting in a truly physiological relevant neural model.
