Outline of Final Research Achievements

The purpose of this study is to establish a new research system linking molecular dynamics (MD) calculations and genetic analysis to reveal the full picture of the signaling pathways by which nanostructures on metal substrate surfaces influence the genes that control the differentiation, proliferation, and apoptosis (spontaneous death) of cells adhering to them.
Part of the diversity of integrin roles in cell adhesion was revealed by a synergistic combination of experiments (cell culture and genetic analysis) and calculations (MD and Monte Carlo simulations). Furthermore, the research results were used to create artificial high cell density tissues.
