Abstract
Neural precursor cells (NPCs) are promising grafts for treatment of traumatic CNS injury and neurodegenerative disorders because of their potential to differentiate into neurons and glial cells. When designing clinical protocols for NPC transplantation, it is important to develop alternatives to direct parenchymal injection, particularly at the injury site. We reasoned that since it is minimally invasive, intrathecal delivery of NPCs at lumbar spinal cord (lumbar puncture) represents an important and clinically applicable strategy. We tested this proposition by examining whether NPCs can be delivered to the injured cervical spinal cord via lumbar puncture using a mixed population of neuronal-restricted precursors (NRPs) and glial-restricted precursors (GRPs). For reliable tracking, the NPCs were derived from the embryonic spinal cord of transgenic donor rats that express the marker gene, human placental alkaline phosphatase, under the control of the ubiquitous Rosa 26 promoter. We found that mixed NRP/GRP grafts can be efficiently delivered to a cervical hemisection injury site by intrathecal delivery at the lumbar cord. Similar to direct parenchymal injections, transplanted NRP/GRP cells survive at the injury cavity for at least 5 weeks post-engraftment, migrate into intact spinal cord along white matter tracts and differentiate into all three mature CNS cell types, neurons, astrocytes, and oligodendrocytes. Furthermore, very few graft-derived cells localize to areas outside the injury site, including intact spinal cord and brain. These results demonstrate the potential of delivering lineage-restricted NPCs using the minimally invasive lumbar puncture method for the treatment of spinal cord injury.
