• Designed structure-based fusion proteins (e.g., elastin-like polymers, silk-like polymers).
• Incorporated cell-bound growth factors (e.g., bFGF, EGF) and cell adhesion molecules (e.g., E-cadherin).
• Developed hybrid systems combining recombinant proteins with synthetic polymers.

Main Results:

• Demonstrated the synthesis of functionalized protein-based polymers with controlled sequences and lengths.
• Showcased the creation of stimuli-responsive and biodegradable synthetic ECMs.
• Highlighted the ability to engineer cell recognition and binding domains within synthetic ECMs.
