Co-culturing of a Dorsal Root Ganglion Explant with Schwann Cells for Neuron Myelination

Executive Industry Relevance

In vitro co-culture of dorsal root ganglion (DRG) explants with Schwann cells provides a controlled system to interrogate mechanisms of peripheral neuron myelination. This model enables predictive evaluation of neuron-glia interactions and supports early-stage target validation for therapies addressing demyelinating neuropathies. Its reproducibility and quantitative outputs position it as a foundational tool for preclinical neurobiology pipelines.
