Development of predictive in vitro assays suitable for safety and efficacy testing is of high interest for improving the drug development process and reducing drug attrition. Recently, there has been a great interest in using stem cells as tools for screening compounds during early drug development. Cardiomyocytes, neuronal progenitors, hepatocytes, and hematopoietic stem cells have all been shown to be attractive cell models for performing a variety of assays. Typically, such assays are performed using high content imaging and analysis (HCA) that allows individual assessment of cell response and multi-parametric outputs. However, there is a need for higher throughput methods with similar sensitivity. Here we present results obtained from the SpectraMax® Paradigm® Plate Reader for performing toxicity assessment of various compounds using stem cell derived cell models in a high throughput manner. The system is configured for cell-based assays with a highly sensitive direct bottom fluorescence read. Plates can be scanned using “Well Scan” or “On-The-Fly” read types. Several viability markers were evaluated including Calcein AM, actin, and mitochondrial stain. We have characterized a number of known hepatotoxic compounds and IC50 values were determined. Excellent agreement was found between plate reader and HCA results.
