Abstract:
Collagen mimetic peptides (CMPs) incorporating the triple-helical sequence or/and integrin-binding sequence were designed. To evaluate biocompatibility of CMPs in vitro, fibroblast cells (L929) were cultured. The proliferation and attachment of cell were observed in certain time. It is demonstrated that all CMPs had no obvious effect on the proliferation of L929 cells. The results also show that all CMPs promote migration and attachment of L929 to the coated surface. And the cells attachment shape and proliferation rate of L929 were good. After coating with CMP27 which containing the triple-helical sequence and integrin-binding sequence, the cell adhesion and spreading of L929 were significantly improved compared with others, and comparable to that observed on type I collagen. The triple-helical sequence and the integrin-binding sequence were shown to be important roles on promoting cell adhesion collaboratively. Therefore, CMP is effective for improving the bioactivity of cell adhesion, and could be potentially used as an adhesive for biomedical application. Moreover, this study provided new insights in designing other peptide-based bioactivity materials.
