Outline of Final Research Achievements |
Effect of the phenotypic changes by gene mutation on its microenvironment and growth dynamics of cancer cells (tumorigenesis) are studied using a mathematical model made up from the combination of cellular Potts model (CPM) and multistage IPP model. Two different cellular properties, i.e. elastic property and adhesion property of cell membrane, are introduced to study its effect on the tumorigenesis. Four different types of cells are mathematically constructed and sixteen different combinations of these four cells are incorporated into multistage dynamics of carcinogenesis. Simulation results show that the combination of the phenotypic changes affect the emergence and growth of the tumor, for example, state of the exponential growth of cancer cells, ratio of the number of the cancer cells in system is regulated by the type of phenotypic changes, and no tumor state are found.
