Context:
Bone marrow stromal cells (BMSCs) can be differentiated into neuronal cells and are used to treat spinal cord injury (SCI).
Objective:
This study investigated whether electroacupuncture enhances BMSC's effects on SCI in rats.
Design:
The effects of transplantation of phosphate-buffered saline or BMSC, electroacupuncture, and a combination of BMSC transplantation and electroacupuncture on SCI were evaluated using a combined behavioral score (CBS). Expressions of neuronal marker neuron-specific enolase (NSE) and gliocyte-specific marker glial fibrillary acidic protein (GFAP) of transplanted BMSC were detected using immunohistochemistry to assess the effect of electroacupuncture on differentiation of BMSC into neuronal cells.
Results:
The combination of BMSC transplantation and electroacupuncture significantly alleviated CBS in rats with SCI compared with the separate treatment of BMSC or electroacupuncture. In addition, electroacupuncture increased the NSE- and GFAP-positive transplanted BMSCs in spinal cord.
Conclusion:
Combined treatment showed a better effect, and the mechanisms may be partially caused by enhanced differentiation of BMSC into neuronal cells. Future studies are needed to confirm this.
