Injectable hydrogel for central nervous system tissue repair
Development of cystic cavities following traumatic spinal cord injury is a major hurdle for regenerative approaches to improve functional recovery.Axonal regeneration from severed host neurons would not occur in the cystic spaces without the presence of proteinaceous extracellular matrix (ECM).Infiltration of endogenous or grafted stem or progenitor cells would be greatly diminished in the fluid-filled cysts.Implantation of scaffolding biomaterials has been regarded as a promising approach to overcome this problem (Tsintou et al., 2015).Indeed, successful obliteration of experimental spinal cord lesions was reported using predesigned solid type of scaffolds (Teng et al., 2002;Hwang et al., 2011).Considering irregular and unpredictable geometry of human spinal cord lesions, however, clinically useful materials should be injectable to accommodate highly variable nature of traumatic lesions.Here, we discuss advantages and disadvantages in employing injectable hydrogel scaffolds to bridge cystic cavities following spinal cord trauma.In addition, we present our recent study where injectable hydrogel successfully prevented cavity formation by promoting extracellular matrix remodeling (Hong et al., 2017).
