Abstract

The development of biomaterials with controllable interfacial features which have the capability to instruct cellular behavior are required to produce functional scaffolds for the treatment of spinal cord injury (SCI). Here, poly-ɛ-caprolactone surfaces were biofunctionalized via layer-by-layer (LbL) deposition. The polyelectrolytes employed in this LbL technique were heparin and poly-L-lysine (PLL), the latter being chosen to improve cell adhesion and the subsequent cellular function of in vitrocultured neural progenitor cells. Material characterization results confirmed the deposition of well structured multilayers. Cell culture studies revealed significant differences in the cellular resp..
