Representative pictures of toluidine blue-stained semi-thin cross-sections of distal nerve segments at 16 weeks post-surgery. Images show healthy nerve segments (A) serving as control compared to distal nerve segments of reconstructed median nerves (B–F). (B) Example of no axonal regeneration from the CNG[F] group. Examples of regenerated nerve samples from the ANG group (C), CNG group (D), CNG[F] group (E), and corrCNG[F] group (F). White scale bars display 10 μm.
