The latency and amplitude of SCEP at the end of 8 weeks after MSCs transplantation and EA treatment. A. After spinal cord transection surgery, the latency of SCEP was significantly prolonged in Op-control group as compared with the Sham-control group (* indicates P < 0.05). However, the MSCs+EA group showed a significant recovery of the latency (# indicates P < 0.01, as compared to the Op-control group; $ indicates P < 0.05, as compared to the EA/MSCs group). B. After spinal cord transection surgery, the amplitude of SCEP was significantly declined in the Op-control group as compared to the Sham-control group (* indicates P < 0.05). However, in the MSCs, EA, or MSCs+EA group, the amplitude of SCEP was significantly recovered as compared with the Op-control group (# indicates P < 0.05). The MSCs+EA group showed a significant recovery of the amplitude as compared to the EA or MSCs group ($ indicates P < 0.05). Data = means ± SD.
