Abstract (original English)

Spinal cord injury (SCI) leads to myelin breakdown and extensive neuronal loss around the injury site due to increased oxidative stress. This study aims to develop a comprehensive platform incorporating scaffolds, therapeutic agents, and stem cells to restore structures and pathways in SCI. Scaffolds were created through the electrospinning of a PCL/functionalized multi-walled carbon nanotube (f-MWCNTs) composite, which was then coated with liposomal ellagic acid (EA@lip) and seeded with adipose-derived mesenchymal stem cells (ADMSCs). The optimal drug concentration was determined by conducting MTT and DPPH assays through three different time points. After assessing the biocompatibility and anti-inflammatory properties of the scaffolds for ADMSCs, the implant was tested in a rat model of dorsal hemisection. The female Wistar rats were divided into six groups (n = 10): Sham, SCI, SCI + PCL/f-MWCNTs (PCs), SCI + scaffolds + EA@lip (PC/N), SCI + scaffolds + ADMSCs (PC/C), and SCI + scaffolds + EA@lip + ADMSCs (PC/N/C). In the second week, biochemical analyses were conducted to evaluate oxidative stress in the animals' blood. Throughout the study, the motor function of the animals was monitored. After six weeks, the rats were subjected to real-time PCR and histological analysis, utilizing Cresyl Violet/Luxol Fast Blue staining and evaluating the expression of the genes COX2, GPX1,
