Mesenchymal-Stem-Cell-Based Strategies for Retinal Diseases.

Area of Science:

• Ophthalmology and Regenerative Medicine

Background:

• Retinal diseases cause irreversible vision loss, with limited treatment success.
• Mesenchymal stem cells (MSCs) are investigated for retinal disease therapy.
• Direct MSC transplantation faces challenges due to retinal barriers.

Purpose of the Study:

• To review the therapeutic potential of MSCs and MSC-derived extracellular vesicles for retinal diseases.
• To summarize current strategies for utilizing these cell-based and cell-free approaches.

Main Methods:

• Review of preclinical studies on MSC therapy for retinal degeneration.
• Analysis of the role of paracrine effects in MSC-based treatments.
• Evaluation of MSC-derived extracellular vesicles as a cell-free therapeutic alternative.

Main Results:

• Direct MSC transplantation efficacy is limited by retinal barriers.
• The paracrine effect of MSCs is a key mechanism in treatment.
• MSC-derived extracellular vesicles present a promising cell-free therapeutic strategy.

Conclusions:

• MSC-derived extracellular vesicles offer a novel and effective cell-free therapeutic approach for retinal diseases.
• This strategy bypasses the limitations of direct cell transplantation, holding potential for vision restoration.
