Cell-Based Therapies for Rotator Cuff Injuries: An Updated Review of the Literature

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biotechnology

Background:

• Rotator cuff injuries are common musculoskeletal conditions.
• Non-surgical treatments are sought to avoid invasive procedures.
• Mesenchymal stem cells (MSCs) offer potential regenerative capabilities.

Purpose of the Study:

• To review non-surgical treatment options for rotator cuff injuries.
• To evaluate the potential of mesenchymal stem cells (MSCs) in regenerative therapy for rotator cuff tears.
• To assess the current evidence from preclinical and clinical studies regarding MSCs for rotator cuff repair.

Main Methods:

• Review of existing literature on non-surgical rotator cuff treatments.
• Analysis of in vitro studies on MSC mechanisms.
• Examination of animal studies investigating MSC efficacy.
• Assessment of human clinical trials, including randomized controlled trials (RCTs).

Main Results:

• In vitro studies show MSCs modulate tendon gene expression and microenvironment.
• Animal studies demonstrate MSCs reduce inflammation, improve remodeling, and enhance tendon strength.
• Human trials suggest MSCs may lower retear rates and improve outcomes, but RCT results are mixed.
• Cell-based therapies exhibit a favorable safety profile.

Conclusions:

• Mesenchymal stem cells (MSCs) present a promising regenerative approach for rotator cuff injuries.
• Standardized investigations and rigorous clinical trials are essential to confirm MSC efficacy.
• Further research is required to establish optimal protocols and validate long-term patient benefits.
