Figure 2.

LN-1 and NGF distribution in step-gradient anisotropic scaffolds. Figure 2A is a schematic of a NGC connected to nerve ends, with four layers of gels in it (A). The darker shades of gel represent increasing concentration of LN-1. Gel 4 has higher concentration of LN-1 than gel 3 and so on (Fig. 2B). Similarly gel 4 has higher concentration of NGF-loaded LMTs than gel 3 and so on (Fig. 2C). While LN-1 gradient is immobilized, with time, NGF will diffuse and form a smooth gradient.
