Abstract
In the study of neurodegenerative diseases, it is imperative to study the cellular and molecular changes associated with pathogenesis in the relevant cell type, central nervous system neurons. The unique compartmentalized morphology and bioenergetic needs of primary neurons present complications for their study in culture. Recent microculture techniques utilizing microfluidic culture devices allows for environmental separation and analysis of neuronal cell bodies and neurites in culture. Here, we present our protocol for culture of primary neurons in microfluidic devices and their chronic treatment with the Parkinson's disease (PD) relevant toxicant rotenone. In addition, we present a method for reuse of devices for culture. This culture methodology presents advantages for evaluating early pathogenic cellular and molecular changes in neurons in a compartment-specific manner.
