Abstract
Studying interactions between neural cells and glial cells in vitro remains an essential tool for scientists worldwide, and with the addition of oxygen-glucose deprivation (OGD) can be particularly useful for identifying mechanisms related to ischemic stroke-related injury and repair. In developing these protocols in the lab, however, we discovered the limitation of co-culturing immune cells with pure neuronal cultures as the standard media for immune cells impair neuronal growth and vice versa. Thus, we optimized a mixed cortical cell culture system that does not require the use of glial-conditioned media to support the viability and growth of neurons but can nonetheless be used to quantify neuronal survival and dendritic arborization. The following methods provide a guide as to how to culture mixed cortical cells from mouse pups (postnatal day 0-2). Additionally, we demonstrate how to co-culture mixed cortical cells with immune cells (e.g., B cells) to study neuro-immune interactions in vitro.
