The objective of this study was to construct the heparin sulfate-collagen pro-tein-based scaffolds and to explore its effects on the proliferation and differentiation abilities of neural stem cells(NSCs).The heparin sulfate-collagen protein-based scaffolds were produced by injection molding/freezing/cross-linking technique.The proliferation ability was detected by MTT and the dif-ferentiation ability was detected by immunofluorescence technique.The results indicate that the heparin sulfate-collagen protein-based scaffolds with porous and longitudinal parallel structures are successfully constructed.The NSCs grow well in the pores of scaffold and still maintain the prolif-eration and differentiation abilities.It is concluded that the scaffolds possess stable porous and longi-tudinal parallel structures and great biocompatibility to NSCs.The combination of scaffold and NSCs may suggest a possible treatment strategy for spinal cord
