Regenerated sciatic nerves 6 months after surgery in the four groups. MBP (A-D, red), S100 (E-H, red), and NF-H (I-L, red) staining of regenerated sciatic nerves in the SCLC-L, SCLC-M, SCLC-H and SNSC. Green: GFP. Yellow: co-located site. Blue: DAPI. (M-P) Perineurium-like structures (asterisk), unmyelinated Schwann cells (white arrow), and myelinated Schwann cells (black arrow) were found in regenerated sciatic nerves by TEM. (Q) Percentage of GFP+ cells co-located with MBP, S100, and NF-H. *P < 0.001. Bar = 5 μm.
