Reports development of a biomimetic bilayered small-diameter vascular graft combining electrospun polyurethane with a gelatin–elastin hydrogel to mimic arterial mechanics and support endothelial cells.
Key Takeaways
- The bilayer graft achieved arterial-like compliance of about 10.93% per 100 mmHg while maintaining burst pressure above 12,000 mmHg.
- Hemocompatibility tests showed low hemolysis ratios and limited platelet adhesion and activation on the electrospun polyurethane layer.
- HUVEC in vitro assays demonstrated favorable attachment, spreading, and proliferation over seven days on the graft surface.
