Laminin-Coated Electronic Scaffolds with Vascular Topography for Tracking and Promoting the Migration of Brain Cells After Injury

Scientists showed that 32 individually addressable platinum microelectrodes integrated into laminin-coated branched polymer scaffolds stereotaxically injected to span a hydrogel-filled cortical lesion and deeper regions in the brains of mice promoted neural regeneration while allowing for the tracking of migrating host brain cells into the lesion.
