Outline of Final Research Achievements |
Extracellular matrix proteins are important factor to maintain the stem cell culture in vitro. Multi-extracellular matrix derived active peptides immobilized chitosan matrices were developed to construct the cell culture scaffold. We immobilized various integrin binding peptides on chitosan matrix to investigate the integrin-integrin cross-talks between different integrin subtypes using multi-peptide-chitosan matrices. The biological activities of multi integrin binding peptide-chitosan matrices could enhance by the optimized combinations and mixture ratios of different active peptides. Further, fibronectin mimicked multi integrin binding peptide-chitosan matrices could develop using the fibronectin derived peptides. These findings are important to control the biological activities of cell culture scaffold to culture the stem cell.
