Membrane extensions are associated with proper anterior migration of muscle cells during Caenorhabditis elegans embryogenesis

► We observe the membrane dynamics of migrating embryonic muscle cells. ► We observe an anterior migration event involving long membrane protrusions. ► Laminin, ina-1, vab-2/vab-1, and sax-3 required for anterior muscle migration. ► Neuronal organization required for proper ventral anterior muscle migration.
