In this study, a new design of graded tubular scaffolds have been developed for the performance enhancement in vascular tissue engineering.The graded poly-L-lactide（PLLA） and gelatin fibrous scaffolds produced by electrospining were then characterized. The morphology,degradability, porosity, pore size and mechanical properties of four tubular scaffolds（graded PLLA/gelatin, layered PLLA/gelatin, PLLA and gelatin scaffolds） have been investigated. The tensile tests demonstrated that the mechanical...
