Neuronal relays can form between injected neural stem cells (NSCs) and surviving neurons,
possibly improving recovery after spinal cord injury (SCI). Cell delivery methods of single or
multiple bolus injections of concentrated cell suspensions thus far tested in preclinical and
clinical experiments are suboptimal for new tract formation. Nonuniform injectate dispersal is
often seen due to gravitational cell settling and clumping. Multiple injections have additive …
