Postnatal histogenesis in the peripheral nervous system.

The issue of postnatal neurogenesis has gained great importance over the last few years and the recent amazing scientific advancements, changing our viewpoint on the long-lasting "no new neurons" dogma, have opened promising new perspectives on the treatment of the damaged nervous system. While most of the researchers have focused on the central nervous system, the peripheral nervous system has received little attention so far with respect to postnatal histogenesis. To attract scientific attention on this issue, the present article was written with the aim of reviewing the body of literature on postnatal histogenesis in the various districts of the peripheral nervous system, from the historical roots to the most recent reports.
