In this study, naturally derived hydrogels including collagen, hyaluronic acid(HA) and sodium alginate were selected as the main components and functionalized with laminin to produce 12 types of scaffolds. Applied with rat neural stem cells(r NSCs) cultured in vitro, the comparison of the biocompatibility and functions among these scaffolds was studied. The results showed that collagen and HA based scaffolds possessed threedimensional porous structures to support r NSCs adhesion after being cultured for 7 d...
