FIG. 3.

Histologic evaluation of regenerated RLNs at one, four, and eight weeks postimplantation in the PCL/F127 NGC and silicone tube groups. No nerve regeneration was detected in the silicone tube group over the eight-week study period. By contrast, continued nerve regeneration of the resected segment was observed at four weeks in the PCL/F127 NGC group, and the regenerated nerve looked structurally normal in the PCL/F127 NGC group at eight weeks (toluidine blue stained;×12.5; *, regenerated RLNs).
