Spinal cord injuries can be life-changing and alter many important neurological functions. Unfortunately, clinicians have relatively few tools to help patients regain lost functions.
In APL Bioengineering, by AIP Publishing, researchers from UCLA have developed materials that can interface with an injured spinal cord and provide a scaffolding to facilitate healing. To do this, scaffolding materials need to mimic the natural spinal cord tissue, so they can be readily populated by native cells in the spinal cord, essentially filling in gaps left by injury.
“In this study, we demonstrate that incorporating a regular network of pores throughout these materials, where pores are sized similarly to normal cells, increases infiltration of cells from spinal cord tissue into the material implant and improves regeneration of nerves throughout the injured area,” said author Stephanie Seidlits.
