Emerging tissue engineering strategies for the corneal regeneration

Area of Science:

• Ophthalmology and Regenerative Medicine
• Biomaterials and Tissue Engineering

Background:

• The cornea, the eye's outer layer, is vulnerable to diseases impacting vision.
• Corneal transplantation is a common surgical solution, but faces significant challenges.
• Limited donor tissue availability and transplantation failure hinder effective corneal grafting.

Purpose of the Study:

• To review current advanced regenerative medicine approaches for corneal regeneration.
• To discuss the limitations of existing methods in corneal repair.
• To explore emerging techniques, such as 5D printing, for alternative tissue reconstruction.

Main Methods:

• Literature review of recent advancements in corneal regeneration.
• Analysis of stem-cell transplantation and scaffold-based technologies.
• Exploration of novel techniques like 5D printing for tissue engineering.

Main Results:

• Advanced regenerative medicine and stem-cell therapies show potential for corneal repair.
• Existing methods have limitations that necessitate further innovation.
• 5D printing presents a novel scaffold-based technology for tissue construction beyond the cornea.

Conclusions:

• Novel techniques, including 5D printing, offer promising alternatives for corneal reconstruction.
• These emerging technologies hold potential for clinical applications in corneal repair, disease modeling, and personalized medicine.
