Summary
This research review explores different regenerative strategies for treating damaged peripheral nerves using stem cells and evaluates their effectiveness in various animal models.
Research Methodology
The authors conducted an extensive review of several databases to gather relevant research data. The databases included Google Scholar, Springer, Elsevier, Egyptian Knowledge Bank, and PubMed. The keywords used for the search included terms related to peripheral nerve damage, such as Radial Nerve, Sciatic Nerve, Animals, Nerve regeneration, and Stem cell.
- The goal was to examine the various methods considered for the regeneration of Peripheral Nerve Injuries (PNI).
Findings from the Review
The review presented several tables that demonstrated various forms of regenerative medicine used in the treatment of PNI. Notably, different types of stem cells: adipose-derived stem cells, bone marrow stem cells, Human umbilical cord stem cells, and embryonic stem cells were found to be particularly effective in the healing process of damaged nerves.
- These stem cells contributed to the reconstitution and functional recovery of the damaged nerve which was evaluated using physical, histological, Immuno-histochemical, and biochemical evaluations.
- The study shone light on the best regenerative strategies that assist in rapid peripheral nerve regeneration in different animal models such as horses, dogs, cats, sheep, monkeys, pigs, mice, and rats.
Conclusions from the Research
Traditional surgical methods such as neurorrhaphy, autogenic nerve transplantation, and Schwann cell implantation have limits in their power of recovery, especially in cases of large nerve defects. However, stem cell therapy, particularly those using mesenchymal stromal cells, have shown to have a high potential for differentiation, providing an opportunity to renew and form new nerves and restore their function.
- Stem cell therapy offers a promising alternative for the treatment of peripheral nerve injuries, going beyond the limitations of old surgical attempts.
