Antipolar Cell-cell Adhesion-causing Collective Motility Disorder
Katsuyoshi Matsushita, Koichi Fujimoto, Mami Matsumoto +1
In this study, we aim to theoretically investigate antipolar cell-cell adhesion, in which adhesion sites are located on the opposite side of the leading edge of migrating cells, as…
Skewed weak and Pareto-tailed strong interactions accompany community diversity and complexity
Takuya Hojo, Taiko Arakaki, Koichi Fujimoto
Ecological communities are often characterized by many weak and few strong interspecific interactions, yet their quantitative structure, generative basis, and links to community-le…
3D mechano-geometric multicellular model of apical stem cell-driven plant morphogenesis
Naoya Kamamoto, Koichi Fujimoto
The orientation of cell division is a major determinant of three-dimensional plant morphogenesis. Whether and how a simple division orientation rule explains the establishment of s…
Delayed control driven oscillations in plant roots
Riz Fernando Noronha, Kunihiko Kaneko, Koichi Fujimoto
Arabidopsis roots show oscillatory growth patterns on homogeneous agar surfaces, whereas other plants, such as maize, do not. Although several explanations have been proposed, a si…
Motion Ordering in Cellular Polar-polar and Polar-nonpolar Interactions
Katsuyoshi Matsushita, Taiko Arakaki, Koichi Fujimoto
We examine the difference in motion ordering between cellular systems with and without information transfer to evaluate the effect of the polar--polar interaction through mutual gu…
