Implication

Hybrid biofabrication strategy enhances mechanical integrity and cellular adhesion in vascular grafts, suggesting promising applications.

Key Points

  • Mechanically robust tubular scaffolds are crucial for vascular tissue engineering and remain a significant challenge.
  • Combining 4D printing with melt electrowriting improves mechanical integrity and supports suturing and perfusion.
  • Scaffold functionalization significantly enhances cellular adhesion and fibroblast proliferation without compromising structure.
  • The engineered system promotes organized cell layers and reciprocal stabilization between endothelial and smooth muscle cells.
