Neural Progenitor Cells in Migration Assay (1 of 2) (image) Salk Institute Share Print E-Mail Caption These images show the movement of patient-derived neural progenitor cells from a sphere of neurons in a migration assay. How far and quickly the neurons move indicates whether they may behave atypically in the brain.
