Objectives: Spinal cord injury (SCI) is a most debilitating traumatic injury, and cytotherapy is a promising alternative treatment strategy. Here we investigated the effect and mechanism of adipose-derived stem/stromal cells (ASCs) with overexpressing brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT3) (BDNF-NT3) in combination with silk fibroin/chitosan scaffold (SFCS) in SCI. Methods: Female Sprague-Dawley rats were used as an SCI model. SFCS,SFCS and ASCs, or ASCs overexpressing NT3, BDNF, and BDNF-NT3 were implanted into SCI rats....
