| Outline of Final Research Achievements |
For peripheral nerve repair, various modifications have been explored. Here, sciatic nerve gaps in mice were reconstructed in the following groups: nerve conduit alone (C group), nerve conduit coated with induced pluripotent stem cell (iPSc)-derived neurospheres (I group), nerve conduit coated with iPSc-derived neurospheres and basic fibroblast growth factor (bFGF)-incorporated gelatin microspheres (I+F group), and autograft (A group). The fastest functional recovery and the greatest axon regeneration occurred in the A group, followed in order by the I+F group, I group, and C group until 12 weeks after reconstruction. Thus, peripheral nerve regeneration using nerve conduits and functional recovery in mice were accelerated by a combination of iPSc-derived neurospheres and a bFGF drug delivery system. The combination of all three fundamental methodologies was essential and useful for peripheral nerve regenerative medicine.
