Effect of hepatocyte growth factor on peripheral nerve regeneration / 中华创伤杂志

ABSTRACT

Objective To explore the effect of hepatocyte growth factor on peripheral nerve regeneration. Methods Sciatic nerve contusion injury was made by a custom-made clamp in Wistar rats,in which human hepatocyte growth factor expressed by adenoviral vector(Ad-HGF)was injected into the muscle around the injured nerve.The results of nerve regeneration were evaluated by sciatic nerve function index(SFI),muscle wet weight,neural electrophysiology and image analysis. Results Four weeks after sciatic nerve injury,the results of sciatic nerve function index(SFI),muscle wet weight,neural electrophysiology and image analysis showed better nerve regeneration in group injected with HGF than control group(P<0.05). Conclusion Hepatocyte growth factor can promote axon regeneration and functional recovery and is an effective neurotrophic factor for peripheral nerve regeneration after injury.
