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

Area of Science:

• Regenerative Medicine
• Neuroscience
• Biotechnology

Background:

• Peripheral nerve injuries (PNI) pose significant clinical challenges, often resulting in long-term disability.
• Current surgical interventions for PNI yield limited functional recovery, necessitating novel therapeutic approaches.
• Mesenchymal stem cells (MSCs) possess regenerative, immunomodulatory, and neuroprotective capabilities, making them a potential solution for nerve repair.

Purpose of the Study:

• To review current strategies employing MSCs for PNI treatment.
• To highlight the potential of MSCs in enhancing nerve regeneration and functional outcomes.
• To discuss advancements like tissue engineering and MSC transdifferentiation for optimizing therapeutic effects.

Main Methods:

• Literature review of studies utilizing MSCs in the context of peripheral nerve repair.
• Analysis of MSC properties relevant to nerve regeneration (regenerative, immunomodulatory, neuroprotective).
• Exploration of tissue engineering and transdifferentiation approaches for MSC-based therapies.

Main Results:

• MSCs demonstrate significant potential in promoting nerve regeneration and functional recovery following PNI.
• Tissue engineering and transdifferentiation of MSCs into Schwann-like cells offer versatile strategies for personalized medicine.
• Challenges remain in clinical translation, including safety, delivery, dosing, and ethical considerations.

Conclusions:

• MSCs represent a promising therapeutic avenue for peripheral nerve injuries.
• Optimizing MSC-based strategies through tissue engineering and understanding underlying mechanisms is crucial.
• Addressing clinical application challenges is essential for the successful management of peripheral nerve defects.
