	abstract = {The present study aimed to develop a pre-endothelialized chitosan (CH) porous hollowed scaffold for application in spinal cord regenerative therapies. CH conduits with different degrees of acetylation (DA; 4\% and 15\%) were prepared, characterized (microstructure, porosity and water uptake) and functionalized with a recombinant fragment of human fibronectin (rhFNIII                        7-10). Immobilized rhFNIII 
                        7-10 was characterized in terms of amount ( 
                        125I-radiolabelling), exposure of cell-binding domains (immunofluorescence) and ability to mediate endothelial cell (EC) adhesion and cytoskeletal rearrangement. Functionalized conduits revealed a linear increase in immobilized rhFNIII 
                        7-10 with rhFNIII 
                        7-10 concentration, and, for the same concentration, higher amounts of rhFNIII 
                        7-10 on DA 4\% compared with DA 15\%. Moreover, rhFNIII 
                        7-10 concentrations as low as 5 and 20 μg ml
