A self-assembling gel that stimulates nerve regeneration has shown promise as a treatment for paralysis in mice A self-assembling gel injected at the site of spinal cord injuries in paralysed mice has enabled them to walk again after four weeks. The gel mimics the matrix that is normally found around cells, providing a scaffold that helps cells to grow.

Summary: Protein hyper-interleukin-6, a "designer protein" that has to be produced via genetic engineering, enabled a paralyzed mouse to walk again. Spinal cord injuries caused by sports or traffic accidents often result in permanent disabilities such as paraplegia.
