Spinal cord injury and repair is one of the important focus areas in tissue regeneration. Mechanical trauma caused due to factors such as contusion, compression or involuntary stretching induce post-traumatic secondary tissue damage in many Spinal Cord Injury (SCI) patients. Therefore, there is a need for scaffolds that provide a conducive threedimensionsal (3D) environment for injured cells to attach and grow. In this study we propose to synthesize 3D polymeric scaffolds in order to study the mechanical and adhesive properties & the nature of the interactions between hyaluronan-based (HY) biomaterials and cells and tissues both in vitroandin vivo. Here we have synthesized 3D HY-based hydrogels with robust mechanical and adhesive properties and demonstrate the use of this material for neuronal-related applications such as the treatment of SCI. Cell culture and survivability studies were done with NSC-34 cells. Live/Dead assay performed on the cells revealed significant differences in the staining of live cells and showed increased viability and proliferation. The number of live cells in the HY-based hydrogels with 0.1% collagen showed higher cell numbers compared with the other hydrogels. In this study we show that Injectable HYbased hydrogels with high elasticity, comparable to the mechanical properties of nervous tissue have been used in this study to study their biocompatibility and neuroprotective properties and they show better affinity for neuronal cells.
