Stem cell therapies for retinal diseases: from bench to bedside

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Cell Biology

Background:

• The human retina lacks regenerative capacity, necessitating novel therapeutic approaches for blinding diseases.
• Decades of preclinical research support stem cell interventions for retinal conditions.
• Current clinical trials demonstrate a favorable safety profile, warranting further investigation.

Purpose of the Study:

• To provide a systematic review of stem cell therapies for retinal diseases that have progressed to clinical trials.
• To synthesize key concepts and highlight major human studies in the field.
• To discuss current challenges and potential strategies for improving safety and efficacy.

Main Methods:

• Focus on stem cell therapies that have undergone clinical trials.
• Systematic review and synthesis of existing literature and clinical data.
• Analysis of challenges including cell source, delivery, and immune response.

Main Results:

• Clinical trials indicate stem cell therapies are a viable option for retinal diseases.
• Safety profiles are encouraging, but challenges remain.
• Combination therapies, such as with gene therapy, show potential.

Conclusions:

• Stem cell therapy is a promising avenue for treating blinding retinal diseases.
• Addressing challenges in cell source, delivery, and immunogenicity is crucial for success.
• Continued research and technological integration are essential for optimizing therapeutic outcomes.
