Development and Evaluation of a Mouse Neocortical Cells Neurodevelopment Assay to Assess the Effects of Pyrethroids

Stephanie I. Savino, Salve Regina University

Pyrethroid insecticides have been used for more than 40 years and account for 25% of the global insecticide market with household, agricultural and public health applications. With increasing use of pyrethroids over recent years, human exposure to these chemicals is likely. The acute toxicity of pyrethroids to mammalian adults has been documented as moderately toxic by the U.S. Environmental Protection Agency. However, little evidence is available regarding the potential toxicological effects of pyrethroids on mammalian neurodevelopment. In this study, a neurodevelopment assay was developed for future investigation of potential pyrethroid effects on the neuronal development of Mus musculus neocortical cells.
