Developmental Toxicity Assay Based on Real-Time Monitoring of Fibroblast Growth Factor Signal Disruption in Human Induced Pluripotent Stem Cells

Developmental toxicity (Devtox) is typically evaluated in animal models. However, there are challenges in ensuring accuracy, such as false negatives due ...

We describe a protocol for a live-cell luciferase assay system for continuously monitoring fibroblast growth factor (FGF) signal disruption in human-induced pluripotent stem cells (iPSCs). Signal disrupting effects of chemicals are used as an indicator to evaluate toxicity. The assay is reliably predictive of the effects of limb malformation chemicals (AUC = 0.93). The current approach is limited to FGF signal disruption, and combinations with other types of signaling will be required to detect the effects of different toxicants. For complete details on the use and execution of this protocol, please refer to Kanno et al. (2022a).
