“…With the present article, we aim at offering a comprehensive compendium describing how to create neural regeneration devices, either scaffolds or tissue-engineered bio-hybrids, and how to implement the biomolecular processes that will foster the regeneration of the amputated peripheral nerves in a wellorganized and guided manner. For this endeavor, we need a deep understanding of the biomolecular processes that underlie FIGURE 4 | Effects of electric neurostimulation on the macroscopic anatomical structure of an amputated rat trigeminal peripheral nerve (Herrera-Rincon et al, 2011).
