Abstract

Retrograde labeling has become the new "gold standard" technique to evaluate the recovery of injured peripheral nerves. In this study, lentiviral vectors with rabies virus glycoprotein envelop (RABV-G-LV) and RFP genes are injected into gastrocnemius muscle to determine the location of RFP in sciatic nerves. We then examine RFP expression in the L4-S1 spinal cord and sensory dorsal root ganglia and in the rat sciatic nerve, isolated Schwann cells, viral dose to expression relationship and the use of RABV-G-LV as a retrograde tracer for regeneration in the injured rat sciatic nerve. VSV-G-LV was used as control for viral envelope specificity. Results showed that RFP were positive in the myelin sheath and lumbar spinal motorneurons of the RABV-G-LV group. RFP gene could be detected both in myelinated Schwann cells and lumbar spinal motor neurons in the RABV-G-LV group. Schwann cells isolated from the RABV-G-LV injected postnatal Sprague Dawley rats were also RFP-gene positive. All the results obtained in the VSV-G-LV group were negative. Distribution of RFP was unaltered and the level of RFP expression increasing with time progressing. RABV-G-LV could assess the amount of functional regenerating nerve fibers two months post-operation in the four models. This method offers an easy-operated and consistent standardized approach for retrograde labeling regenerating peripheral nerves, which may be a significant supplement for the previous RABV-G-LV-related retrograde labeling study.
