Enhanced Neural Regeneration with a Concomitant Treatment of Framework Nucleic Acid and Stem Cells in Spinal Cord Injury.

Spinal cord injury (SCI), began with a primary injury including contusion and compression, is a common disease caused by various pathogenesis. Characterized disruption of axons and irreversible loss of neurons in SCI, and further damage in spinal cord tissue caused by following secondary injuries such as the formation of glial scar and inflammation, makes it even harder to recover for affected patients. Tetrahedral framework nucleic acid (tFNA), which possesses the capability of promoting neuroprotection and neuroregeneration in vitro, might alleviate the injuries and facilitate the neural tissue regeneration in experimental animal models of SCI. Here, we developed a concomitant treatment of tFNA and neural stem cells (NSCs) for the synergistic therapy in treating the injury of spinal cord. We firstly observed that tFNA could promote cell proliferation of NSCs, then verified that the concomitant treatment of tFNA and NSCs showed the neuroprotective actions by increasing the survival of transplanted NSCs. Furthermore, the recovery of motor function and the tissue regeneration in lesion site of spinal cord achieved best performance in the SCI rats treated with the combination of tFNA and NSCs than others, and the formation of glial scar was least. Our findings provide novel evidence of a promising strategy for synergistic treatment of SCI in the future.
