| Outline of Final Research Achievements |
Controlling the three-dimensional movement of cells is one of the important fundamental technologies of tissue engineering. In this study, we have investigated the design of mechanical conditions of the artifical extraculluar matrix, i.e, the electrospun microgel fiber matrix of photocrosslinkable gelatin capable of modulating the elastic modulus and the degree of fiber bonding. Based on the methodology, we have developed the design technology for three-dimensional microscopic mechanical field to induce the sponteneous functional localization of cells. As one example of its operation, we examined the effect of the mechanical field on the three-dimensional invasion behavior of cancer cells, and successfully designed the mechanical condition of extracellular matrix that captures only malignant cancer cells without penetrating normal cells.
