Abstract

The peripheral nervous system (PNS) consists of nerves that extend beyond the brain and spinal cord, connecting the body to the central nervous system (CNS). Peripheral nerve injuries, caused by trauma, compression, or disease, often result in sensory and motor deficits. In the current study, a nanofibrous neural conduit was developed by loading Inula helenium extract into electrospun PCL/gelatin scaffolds. Then, the scaffolds were characterized in vitro using different analysis methods. Then, the electrospun sheets were rolled up to produce neural conduits. Finally, the healing efficacy of the developed system was investigated in a rat model of sciatic nerve injury. Results showed that the animals that were treated with both treadmill exercise and the Inula helenium extract-loaded conduits had significantly better functional recovery and histopathological recovery. ELISA assay showed that the hybrid treatment method increased tissue concentrations of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) and decreased tumor necrosis factor- α (TNF- α) tissue levels.
