Spinal cord injury (SCI) affects millions worldwide, and current treatments often fail to fully restore lost function. New approaches using stem cells to create neural progenitor cells (NPCs) are promising. These NPCs can be transplanted to the injury site to help regenerate the spinal cord. Direct reprogramming, which converts non-neuronal cells into NPCs without going through a pluripotent state, is a particularly attractive strategy. This method allows for the production of large numbers of NPCs in the lab for transplantation. However, a major challenge is the low efficiency of direct reprogramming, which hinders its use in clinics. This review explores new targets, tools, and approaches, like mechanotransduction and electrical stimulation, to improve reprogramming efficiency for spinal cord injury treatment.
Improving the efficiency of direct pro-neural reprogramming could lead to more effective cell-based therapies for spinal cord injury.
Identifying novel targets like mitochondria, nucleoli, and G-quadruplexes can open new avenues for therapeutic intervention.
Combining drNPCs with tissue-engineered scaffolds and bioactive molecules may enhance cell survival and differentiation in the injury site.
