Hydrogel scaffolds with regularly spaced pores encourage spinal cords cells to grow, improve regeneration of nerve cells. Researchers 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. The researchers show how the pores improve efficiency of gene therapies administered locally to the injured tissues, which can further promote tissue regeneration.
Spinal cord injuries can be life-changing and alter many importa...
