Outline of Final Research Achievements |
This research attempted to combine the advantages of the control of growth factors and the adjustable mechanical properties of the scaffold, to provide variety choice for scaffold design. We focus on the heparin as a growth factor-immobilization agent, and we prepared heparin-conjugated collagen gel. We also built crosslink between the collagen fibers to change the mechanical properties. By using heparin-conjugated collagen gel and immobilizing some growth factors, the survival and functions of cultured cells were up-regulated. On the other hand, the research on the change of the mechanical properties, which could cause by the cross-linking level of the substrate itself, showed the influence on the state of the cells. In the future, this study would contribute to the investigation of the mechanisms underlying cell-fate decisions.
