Live imaging of migrating MGE cortical interneurons in a 3D Matrigel assay under control conditions. Medial ganglionic eminence (MGE) explant left, outgrowth area right. Interneurons migrating away from E14.5 Dlx5/6-CIE MGE explants were imaged for 12 hours in control conditions. Representative tracks from 5 cells demonstrate interneurons migrating in consistent, straight trajectories.
