| Outline of Final Research Achievements |
Adhesion of fibroblasts (NIH3T3) on silk fibroin, incorporated with an azide-bearing unnatural amino acid (AzPhe), was investigated after being modified with cell adhesive RGD peptides or cell repulsive polyethylene glycols (PEG). When the RGD peptide was ligated on silk fibroin, fibroblasts with extended forms became abundant although number of adhered cells did not increase. When the PEG chain was ligated on silk fibroin, number of adhered cells significantly decreased. It was demonstrated that cell patterning on silk fibroin is possible by partially destroying azide groups by UV irradiation.
