| Outline of Final Research Achievements |
Biological organisms have complex form, like fractal structure. However, the mechanismn how the fractal structure is generated remain to be elucidated. In the present study, we use two biological systems, retina vasculature and skull suture interdigitation, and formulated biologically plausible mathematical model. Then we analytically showed that the model can generate patterns that show scaling behavior. In retina vasculature, combination of physiological law of vessel radii (Murray's law) and equal bifurcation can lead to the scaling behavior. In skull suture, noise term in the original PDE model can lead to the scaling behavior.
