Low-Level Laser-Accelerated Peripheral Nerve Regeneration within a Reinforced Nerve Conduit across a Large Gap of the Transected Sciatic Nerve in Rats

Figure 9

Transverse sections with osmium tetroxide of sciatic nerves from the medial segment of the regenerated nerve tissue twelve weeks after operation in the (a) GGT and (b) GGT/LS groups. Scale bars represent 100 μm. Arrow heads indicate myelinated nerve fibers (yellow), unmyelinated nerve fibers (white), and blood vessels (red).
