FIG. 2.

An illustration of how fiber geometry affects neurite extension from dorsal root ganglia (DRG) on electrospun fibers. The blue/green objects in the illustrations on the right side of the figure indicate the DRG body. When electrospun fibers are aligned and the fiber diameter is above 750 nm, neurites extend along the fibers (A). When electrospun fibers are aligned but the fiber diameter is below 750 nm, neurites will still follow the fibers, but the neurites tend to be shorter and appear to wander in less of a straight line along the fibers (B). When electrospun fibers are randomly aligned, neurites tend to grow in all directions (C). Color image is available online at www.liebertpub.com/neu
