Abstract:
Spinal cord injury (SCI) is a traumatic injury to the spinal cord which is not a consequence of the disease. Mesenchymal stem cells (MSCs) have gradually become one of the most used stem cells in research and clinic trial. Based on the previous reports employed the cells ranged from 4 • 105 to 1 • 106, the present study was performed to figure out the best number of MSCs for transplantation of the chronic SCI. Magnetic nanoparticles were used for proving the precise transplantation strategy. Using magnetic resonance imaging (MRI), diffusion tensor imaging (DTI), diffusion tensor tractography (DTT), and behavior testing evaluations, we focused the effect of varying numbers of MSCs on reducing lesion cavity and post–traumatic syrinx formation, suppressing glial scar formation, enhancing neuronal fibers remodeling, promoting axonal regeneration and sprouting, improving vascularization, ameliorating the neuronal factors expressional level, and function improvement. Magnetic nanoparticles were precisely transplanted into the post–traumatic syrinx (PTS). MSCs can restore function after chronic SCI through stimulating the regeneration and sprouting of the axons, reducing the formation of PTS. The effect of MSCs on PTS management and functional improvement post chronic SCI was cell number–dependent, and within the range of 4 • 105 to 1 • 106, 1 • 106 cells were proved to be the best dose.
