A new 3D collagen-like protein/aldehyde-functionalized dextran (CLP-AD) hydrogel was developed for tissue engineering. This printable biomaterial supports cell viability and migration, offering a promising alternative to animal-derived collagen for soft tissue repair.
Area of Science:
- Biomaterials Science
- Tissue Engineering
- Regenerative Medicine
Background:
- Traditional collagen hydrogels face limitations including disease transmission risk and batch variability.
- Developing advanced biomaterials is crucial for effective soft tissue repair and regeneration.
Purpose of the Study:
- To develop a novel, animal-free 3D collagen-like protein/aldehyde-functionalized dextran (CLP-AD) hydrogel.
- To assess the CLP-AD hydrogel's suitability for 3D bioprinting and soft tissue engineering applications.
Main Methods:
- Fabrication of the CLP-AD hydrogel via Schiff base reactions under physiological conditions.
- Characterization of hydrogel properties including gelation, swelling, degradation, rheology, and cytocompatibility.
- In vitro evaluation using human endothelial cells and umbilical cord-derived mesenchymal stem cells (UC-hMSCs).
Main Results:
- The CLP-AD hydrogel exhibited favorable gelation, swelling, degradation, and cytocompatibility.
- Rheological analysis confirmed viscoelastic and self-healing properties suitable for dynamic environments.
- High cell viability, migration, and encapsulation efficiency were observed for endothelial cells and UC-hMSCs.
Conclusions:
- The CLP-AD hydrogel is a tunable, 3D-printable biomaterial with excellent cytocompatibility and mechanical properties.
- This novel hydrogel presents a viable, animal-free alternative to collagen for soft tissue engineering and regenerative medicine.
- The CLP-AD hydrogel shows significant potential for applications in soft tissue repair and regeneration.
