Scientists use Axion’s Maestro platform to demonstrate the advantages of iPSC sensory co-cultures on MEAs for moderate-to-high throughput compound screening. 

New pain therapeutics are urgently needed but conventional drug screening methods are expensive, low-throughput, and unreliable. In this study, scientists develop a phenotypic inflammatory nociception model for in vitro drug screening, using Axion’s Maestro Pro multielectrode array (MEA) system to assess sensory neuron-glial co-culture activity and evaluate responses to FDA-approved analgesic compounds in real time. Overall, the researchers conclude that the approach “represents an ‘excellent’ assay based on assay quality metrics and represents a model system for drug ‘hit’ or lead detection,” and add that the stable phenotypic activity observed in the cell models make them ideal for long-term screening.
