Experimental protocol and time points. After adaptive training for 1 week in advance, the rats were randomly divided into four groups for spinal cord injury modeling or sham operation. Two groups were injected with adeno-associated viral (AAV)-N-T3/AAV-IGF-1 or AAV-GFP/AAV-RFP 1 day after surgery. Three rats were then examined by immunofluorescence 4 weeks after surgery to determine the expression of AAV. The other rats received behavioral and electrophysiological evaluations for 10 weeks. After 70 days, all rats were sacrificed for western blotting and immunofluorescence detection.
