Elastic polyurethane bearing pendant TGF-β1 affinity peptide for potential tissue engineering applications

- Elastic degradable polyurethane bearing pendent HSNGLPL peptide.
- The pendant peptide shows high affinity for TGF-β1 conjugating.
- Good extrusion processing ability and can be printed into 3D scaffolds.
- TGF-β1 detached from surface keeps its bioactivity both in vitro and in vivo.
