Spinal cord injuries lead to permanent disabilities due to neuron loss and scar tissue. Gene therapy aims to introduce genes into cells at the injury site, causing them to produce therapeutic molecules that promote tissue repair. Non-viral gene vectors are a safer alternative to viral vectors for gene therapy. They can carry larger DNA sequences and be modified to target specific cell types. Nanocarriers improve gene delivery efficiency into cells. Biomaterial scaffolds can provide structural support for tissue regeneration and act as reservoirs for sustained gene delivery.
Nanocarriers and targeted vectors offer improved methods for delivering therapeutic genes to specific cells within the injured spinal cord.
Combining gene therapy with biomaterial scaffolds promotes axonal regrowth and functional recovery after SCI.
Further research is needed to translate these findings into effective clinical therapies for spinal cord injury patients.
