Evaluation of regenerated nerve fibers at the distal site of nerve grafts at 12 weeks postoperatively. (A) Toluidine blue-stained images and TEM images of transverse sections at the distal site of the harvested nerve grafts. (B) Statistical analysis of the density of myelinated nerve fibers quantified from toluidine blue-stained images. (C) Statistical analysis of the diameter of the myelinated nerve fibers quantified from TEM images. (D) Statistical analysis of the thickness of the myelin sheath quantified from TEM images. (E) Statistical analysis of the diameter-based g-ratio. (F) Statistical analysis of the perimeter-based g-ratio. (G) The scatter diagram of g-ratio versus axon diameter. *P < 0.05 and **P < 0.01 (n = 5).
