Biopolymers and biodegradable smart implants for tissue regeneration after spinal cord injury.

This article reviews recent experimental advances in the development of biosynthetic implants for repair of spinal cord injury.Various important advances in the development of biosynthetic conduits for spinal cord repair have recently been reported. It was found that implantation of freeze dried alginate sponge into completely transected spinal cord supports axonal regeneration across the lesion site. A poly(lactic-co-glycolic acid) scaffold...
