3D Cancer Migration Assay with Schwann Cells.

In pancreatic cancer, neural invasion is one of the most common paths of cancer dissemination. Classically, cancer cells actively invade nerves and cause local recurrence and pain. Three-dimensional (3D) neural migration assay has become a standard tool for scientists to study neural invasion by confronting the involved cell types. This protocol introduces Schwann cells, i.e., the most prevalent cell type in peripheral nerves, in a novel heterotypic, glia-cancer-neuron, 3D migration assay for assessing their relevance in the early pathogenesis of neural invasion. Particularly, this assay allows the monitoring of the early Schwann cell migratory activity.
