Mesenchymal stem cell-based therapy for peripheral nerve injuries: A promise or reality?

Figure 4 Summarized schematic of different designs to enhance nerve guidance conduits (NGCs). Design variations include hollow tubes, multichannel, porous, grooved structures, fiber, or hydrogel fillers. These designs can be used alone or in combination with mesenchymal stem cells or Schwann-like cells for the treatment of peripheral nerve injuries. NGCs: Nerve guidance conduits.
