Sustained delivery of vascular endothelial growth factor mediated by bioactive methacrylic anhydride hydrogel accelerates peripheral nerve regeneration after crush injury.

ABSTRACT: Neurotrophic factors, currently administered orally or by intravenous drip or intramuscular injection, are the main method for the treatment of peripheral nerve crush injury. However, the low effective drug concentration arriving at the injury site results in unsatisfactory outcomes. Therefore, there is an urgent need for a treatment method that can increase the effective drug concentration in the injured area. In this study, we first fabricated a gelatin modified by methacrylic anhydride hydrogel and loaded it with vascular endothelial growth factor that allowed the controlled release of the neurotrophic factor. This modified gelatin exhibited good physical and chemical properties, biocompatibility and supported the adhesion and proliferation of RSC96 cells and human umbilical vein endoth
