Summary
Fish-derived gelatin methacryloyl (GelMA) offers a safe alternative to mammalian GelMA. This study shows fish GelMA exhibits tunable properties and supports cell growth, making it suitable for biomedical applications.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Biomedical Engineering
Background:
- Gelatin methacryloyl (GelMA) is a widely used biomaterial in biomedical applications.
- Current GelMA production relies on mammalian sources, posing risks of disease transmission and religious concerns.
Purpose of the Study:
- To synthesize and characterize GelMA from fish-derived gelatin.
- To evaluate the physical properties and cellular responses of fish GelMA.
- To assess fish GelMA as a potential substitute for mammalian-derived GelMA.
Main Methods:
- Fish gelatin was used to synthesize GelMA via a conventional method.
- Physical properties including mechanical strength, swelling, and degradation were assessed.
- Cell adhesion, proliferation, and viability on fish GelMA hydrogels were evaluated.
Main Results:
- Fish GelMA synthesis was scalable and enabled room-temperature hydrogel fabrication due to lower gelatin melting point.
- Fish GelMA exhibited distinct mechanical, swelling, and degradation properties compared to porcine GelMA, which were tunable.
- High cell viability, adhesion, proliferation, and network formation were observed on fish GelMA.
Conclusions:
- Fish-derived GelMA is a viable, safe alternative to mammalian GelMA.
- Tunable properties of fish GelMA make it adaptable for various biomedical uses.
- Fish GelMA supports robust cell responses, indicating its potential in tissue engineering and regenerative medicine.
