Main Methods:
- Synthesized a biohybrid hydrogel using heparin and peptide-conjugated star-shaped poly(ethylene glycol).
- Incorporated matrix metalloproteinase (MMP)-sensitive and cell-adhesive peptide crosslinkers.
- Utilized the heparin-binding property of vascular endothelial growth factor (VEGF).
Main Results:
- The novel hydrogel demonstrated successful crosslinking with combined MMP sensitivity and cell adhesion.
- The material effectively supported three-dimensional migration of human endothelial cells.
- VEGF binding to heparin within the hydrogel enhanced cellular response.
Conclusions:
