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

Table 1

Morphometric evaluations of regenerated nerves in each group.

Statistical analysis of the nerve fiber density, diameters, thickness, and G-ratios in all groups using the ImageJ software. G-ratio was calculated by dividing the diameter of the axon by fiber diameter. The data are expressed as the . PNI vs. control: ; FGF13 vs. vehicle: ^& and ^&&; FGF13 vs. PNI: ^# and ^##.
