We present an insight of the effects of combination therapy with neurotrophin-3 and neural stem cell on functional recovery after spinal cord injury (SCI). Total RNA was extracted from neural stem cell line C17.2 and reversed transcribed into cDNA. Neurotrophin-3 (NT-3) gene was amplified by PCR and subcloned into plasmid to construct an expression vector pNT-3. A positive clone containing pNT-3, named SHN2, was obtained and used for transplantation. Thirty adult mice received mechanical injury at the T8 vertebra level. Cell survival, NT-3 gene expression, and functional recovery were observed through X-Gal staining, RT-PCR, and open field locomotion, respectively. The results show that NT-3 gene comprising 777 bp nucleotides was cloned and a more than twofold expression was detected when transfected into neural stem cell line C17.2. Quantitative analysis of cellular density revealed a significant increase in SHN2 compared to the control cells (p < 0.01). Thirty days after transplantation, SHN2 showed significant increase near the lesion site. Furthermore, the functional recovery indicated an active effect by detecting Basso-Beattie-Bresnahan (BBB) locomotor rating scale (p < 0.01). In conclusion, combined treatment of neural stem cells and NT-3 gene can facilitate functional recovery. It offers an effective approach to treat SCI.
