Summary
This study engineered a hybrid cornea stromal construct using gelatin methacrylate (GelMA) and decellularized extracellular matrix (ECM). This approach significantly improved optical and mechanical properties for potential corneal transplants.
Area of Science:
- Biomaterials Engineering
- Tissue Engineering
- Ophthalmology
Background:
- Corneal decellularization often compromises extracellular matrix (ECM) microstructure, leading to poor mechanical and optical properties.
- Existing decellularization protocols struggle to preserve essential corneal matrix features.
Purpose of the Study:
- To engineer a hybrid cornea stromal construct combining gelatin methacrylate (GelMA) and decellularized ECM.
- To restore optical and mechanical properties of decellularized corneal matrices.
Main Methods:
- Fabrication of hybrid constructs using GelMA and decellularized bovine cornea.
- Optimization of UV cross-linking energy and impregnation time for GelMA.
- Characterization of optical transmittance, mechanical strength, chemical structure (ATR-FTIR), and degradation profiles.
Main Results:
- Optimized hybrid constructs showed a nearly 10-fold increase in light transmittance (53.6%) compared to decellularized cornea (5.84%).
- Compressive modulus was restored up to 6-fold, approaching native cornea values.
- In vitro studies demonstrated high cell viability and proliferation up to 14 days.
Conclusions:
- The hybrid cornea stromal construct effectively restores optical and mechanical functions lost during decellularization.
- This engineered tissue is a promising candidate for developing advanced corneal transplantation therapies.
