Study design: We evaluated whether combination of chondroitinase (chABC) administration and brain-derived neurotrophic factor (BDNF)-mesenchymal stem cell (MSC) transplantation could provide an optimal effect for the treatment of spinal cord injury (SCI) subjected to complete transection. Objectives: Behavioral assessments and DBA tracing were used to evaluate the effects of combination of chABC administration and BDNF-MSC transplantation on axonal regeneration and functional improvement in SCT rats. Setting: Sichuan, China Methods: Bone mesenchymal stem cells (BMSCs) were cultured and overexpressed BDNF recombinant vector was constructed into MSCs, then transplanted into the impaired spinal cord, together with chABC administration. Finally, the cortical spinal tract regeneration was detected by DBA tracing at 4 weeks post operation, and the expression of nerve growth factor (NGF), BDNF, neurotrophic factor (NT)-3, NT-4, fibroblast growth factor (FGF-2)-2, B cell lymphoma 2 (BCL-2) assaciated X protein (BAX) and BCL-2 in the caudal cord tissues was assessed by reverse transcription-PCR. Results: Animals received both BDNF-BMSC transplantation and chABC administration presented the best functional recovery and obvious axonal regeneration. Moreover, NGF expression was significantly higher than that in the other groups. Conclusion: Co-treated strategy could effectively promote motor functional recovery and axonal regeneration in SCT rats associated with NGF upregulation.
