Abstract

The use of stem cell base therapy as an effective strategy for the treatment of spinal cord injury (SCI) is very promising. Although some strategy has been made to generate neural-like cells using bone marrow mesenchymal stem cells (BMSCs), the differentiation strategies are still inefficiently. For this purpose, we improved the therapeutic outcome with utilize both of N-neurotrophic factor derived Gelial cells (GDNF) gene and differentiation medium that induce the BMSCs into the neural-like cells. The differentiated GDNF overexpressed BMSCs (BMSCs-GDNF) were injected on the third day of post-SCI. BBB score test was performed for four weeks. Two weeks before the end of BBB, biotin dextranamin was injected intracrebrally and at the end of the fourth week, the tissue was stained. BBB scores were significantly different in BMSCs-GDNF injected and control animals. Significant difference in axon counting was observed in BMSCs-GDNF treated animals compared to the control group. According to the results, differentiated BMSCs-GDNF showed better results in comparison to the BMSCs without genetic modification. This study provides a new strategy to investigate the role of simultaneous in stem cell and gene therapy for future neural-like cells transplantation base therapies for SCI.
