FIG. 6.

Longitudinal sections of the regenerated nerve fibers through the Nanopore NGC/NGF and Micropore NGC/NGF. (A, B) Hoechst staining; (C, D) NF-200 staining; (E, F) S100β staining; and (G, H) their merged images (4 weeks after implantation;×100; white arrow, regenerated nerve fiber; black arrow, NGC; red arrow, observation position). For the Nanopore NGC/NGF, the migrating cells were predominantly positioned at the central region in the NGC without attachment on the conduit wall surface. The regenerating nerve fibers were arranged along the longitudinal direction of the conduit. In contrast, for the Micropore NGC/NGF, the cells were scattered without any arrangement, and the regenerated nerve fibers had infiltrated into the porous wall of the conduit.
