Abstract:
Since cell adhesion is important for cell processes such as migration and proliferation, it is a crucial consideration in biomaterial design and development. Based on the fusion of mussel adhesive protein fp151 with laminin-1-originated functional peptides we designed fusion proteins (fLA4, fLG6 and fAG73) and explored their cell adhesion properties. In our study, cell adhesion analysis showed that protein fLG6 and fLA4 had a significantly higher cell adhesion property for A549 than fp151. Moreover, protein fAG73 also displayed a strong adhesion capacity for Hela cells. In conclusion, the incorporation of functional peptides with integrin and heparin/heparan sulphate binding capacity into mussel adhesive protein will promote the application of mussel adhesive protein as cell adhesion biomaterial.
