Meniscus repair: up-to-date advances in stem cell-based therapy

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biotechnology

Background:

• Meniscus injuries impair knee function and can lead to osteoarthritis.
• The meniscus's avascular nature hinders natural healing, making repair challenging.
• Stem cell therapy offers potential for meniscus regeneration.

Purpose of the Study:

• To review recent advances in stem cell-based meniscus repair.
• To identify obstacles to clinical translation of these therapies.
• To propose future directions for stem cell therapy in meniscus repair.

Main Methods:

• Review of scientific literature on stem cell therapy for meniscus repair over the past five years.
• Analysis of mesenchymal stem cells' properties relevant to meniscus regeneration.
• Discussion of current challenges and future perspectives.

Main Results:

• Mesenchymal stem cells are extensively studied for meniscus repair due to their regenerative and immunomodulatory capabilities.
• Significant progress has been made in preclinical and early clinical studies.
• Several hurdles remain for widespread clinical adoption.

Conclusions:

• Stem cell therapy, particularly using mesenchymal stem cells, holds significant potential for treating meniscus injuries.
• Addressing challenges in delivery, integration, and long-term efficacy is crucial.
• Continued research and clinical trials are necessary to realize the full therapeutic benefits.
