Figure 1. Repairing neural damage using implanted or injected materials.

Figure 1

Examples of methods being tested for stimulating regrowth of neurons across damaged parts of the CNS. Left column illustrates engineered (top) and biologically-derived (bottom) materials that are surgically implanted into the damaged part of the CNS to form a porous scaffold upon which axons can regrow. Right column illustrates how various hydrogels can be injected into the damaged area to form a scaffold in situ as well as deliver drugs and therapies locally.
