Fibroblast Growth Factor 13 Facilitates Peripheral Nerve Regeneration through Maintaining Microtubule Stability

Figure 5

FGF13 promotes nerve regeneration after PNI. H&E staining was used to visualize the regenerated nerve fibers in the longitudinal sections of the regenerated segments in the control group, the PNI group, the vehicle group, and the FGF13 group at week 6 after the surgery. Scale bars, 500 μm (a); 50 μm (b).
