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

Figure 1

Analysis of regenerating cables at week 6 after injury. (a) Representative semithin transverse sections of regenerated nerves stained by toluidine blue in four groups; (b) TEM of ultrathin sectioned nerves of the four groups. The gross myelin distribution and regeneration were clearly seen via the lower magnification (2 μm) in the middle panel. The bottom panel enlarged images with the higher magnification of 1 μm were representative individual myelin in each group and not from the middle panel.
