Abstract: Objective To explore the biocompatibility of the Poly(l-lactic acid)(PLLA) nano-fibrous scaffold with spinal cord tissue of rats.Methods PLLA three-dimensional(3D) scaffolds with macro/micro-pores and nano-fibrous structure were fabricated by phase separation from a ternary PLLA/dioxane/water system.MSCs-PLLA nano-fibrous scaffolds complex were constructed in vitro.Twelve SD rats were divided into two groups:control injured group and MSCs transplanted group.T10 spinal cord segment was exposed,and then trans...
