In this video, we have demonstrated how to prepare and maintain compartmented chambers for use in culturing DRG neurons. Done properly, this system allows separation of the cell body from the axon in order to study mechanisms by which neurotrophins signal across long axons. Since there is fluidic isolation between the compartments, it allows for selective stimulation or treatment of one compartment without the other compartments being affected. Compartmented chamber cultures can support other cell types including sympath...

preparation and maintenance of dorsal root ganglia neurons in compartmented cultures

Neurons extend axonal processes that are far removed from the cell body to innervate target tissues, where target-derived growth factors are required for neuronal survival and function. Neurotrophins are specifically required to maintain the survival and differentiation of innervating sensory neurons but the question of how these target-derived neurotrophins communicate to the cell body of innervating neurons has been an area of active research for over 30 years. The most commonly accepted model of how neurotrophin signals reach the cell body proposes that signaling endosomes carry this signal retrogradely along the axon. In order to study retrograde transport, a culture system was originally devised by Robert Campenot, in which cell bodies are isolated from their axons. The technique of preparing these compartmented chambers for culturing sensory neurons recapitulates the selective stimulation of neuron terminals that occurs in vivo following release of target-derived neurotrophins. Retrograde signaling events that require long-range microtubule dependent retrograde transport have important implications for the treatment of neurodegenerative disorders.
