This video illustrates a method for establishing an indirect neuron-astrocyte co-culture using a compartmentalized approach. In this setup, neurons and astrocytes are spatially separated but share a conditioned medium. Neurotrophic factors released by astrocytes promote neuron differentiation and the formation of synaptic connections, suggesting neuron-glia interactions.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation and Cultivation of Cortical Astrocytes NOTE: Complete these steps of the protocol at least 7 d before proceeding to the next steps, as the astrocyte cultures should develop into confluent monolayers before the neurons are prepared. Primary astrocytes are derived from mixed glia…
