Corneal Epithelial Regeneration: Old and New Perspectives

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Stem Cell Biology

Background:

• Corneal blindness is a significant global health issue, with limited treatment options primarily relying on corneal transplantation.
• The corneal epithelium's regenerative capacity is crucial for vision, depending on limbal stem cells and basement membrane integrity.
• Shortages of donor corneas drive research into regenerative medicine for corneal epithelial disorders.

Purpose of the Study:

• To review current basic, clinical, and surgical research in regenerative medicine for corneal epithelial disorders.
• To classify therapeutic approaches based on their cellular or subcellular targets.
• To highlight the potential of regenerative medicine in restoring corneal function and improving tissue viability.

Main Methods:

• Comprehensive literature review of research reports on corneal regenerative medicine.
• Classification of therapeutic strategies based on macro- (cellular) or microscopic (subcellular) targets.
• Analysis of surgical techniques involving stem cell transplantation for corneal regeneration.

Main Results:

• Regenerative medicine is a rapidly advancing field for corneal rehabilitation due to the cornea's exposure to external damage.
• Innovative surgical techniques are being developed to transplant various stem cells for epithelial regeneration.
• Therapeutic approaches are categorized into cellular and subcellular strategies.

Conclusions:

• Regenerative medicine holds significant promise for treating corneal epithelial disorders and combating corneal blindness.
• The development of biological substitutes and advanced cell-based therapies aims to restore corneal function effectively.
• Continued research in regenerative medicine is essential to overcome the limitations of traditional treatments like corneal transplantation.
