ABSTRACT
BACKGROUND: Wnt signaling pathways can stimulate the proliferation and differentiation of neural stem cel s, and promote the repair of spinal cord injury. The electrical field stimulation can change the protein expression of Wnt signaling pathways. QBJECTIVE: To explore the influence of oscil ating electric field on motor function recovery and the expression of Wnt-3a protein in rats with spinal cord injury. METHODS: A total of 36 Sprague-Dawley rats models with spinal cord injury were induced by the Al en’s method. Al rats were randomly divided into oscil ating electric field stimulation group and spinal cord injury group. The stimulating electrodes were added in both groups. The oscil ating electric field stimulation group received oscil ating electric field intervention. RESULTS AND CONCLUSION: At 3 days after model establishment, Basso, Beattie, and Bresnahan (BBB) locomotor rating scale scores and Wnt-3a expression were similar between the oscil ating electric field stimulation group and spinal cord injury group. At 7 and 14 days, significant differences in BBB scores and Wnt-3a expression were detected. These results indicate that oscil ating electric field stimulation can activate Wnt signaling protein in the early stage of spinal cord injury, which may be associated with the promoting effect of oscil ating electric field stimulation on spinal cord injury.
