Collective Cell Movement in Cell-Scale Tension Gradient on Tissue Interface
Katsuyoshi Matsushita, Hidenori Hashimura, Hidekazu Kuwayama +1
In this paper, we examine the emergence of cell flow induced by a tension gradient on a tissue interface as in the case of the Marangoni flow on liquid interface. We consider the m…
Cell Motion Alignment as Polarity Memory Effect
Katsuyoshi Matsushita, Kazuya Horibe, Naoya Kamamoto +1
The clarification of the motion alignment mechanism in collective cell migration is an important issue commonly in physics and biology. In analogy with the self-propelled disk, the…
Curved surface geometry-induced topological change of an excitable planar wave
Kazuya Horibe, Ken-ichi Hironaka, Katsuyoshi Matsushita +1
On the curved surfaces of living and nonliving materials, planar excitable waves frequently exhibit directional change and subsequently undergo a topological change; that is, a ser…
A Mechanical Instability in Planar Epithelial Monolayers Leads to Cell Extrusion
Satoru Okuda, Koichi Fujimoto
In cell extrusion, a cell embedded in an epithelial monolayer loses its apical or basal surface and is subsequently squeezed out of the monolayer by neighboring cells. Cell extrusi…
Network Evolution of Body Plans
Koichi Fujimoto, Shuji Ishihara, Kunihiko Kaneko
Segmentation in arthropod embryogenesis represents a well-known example of body plan diversity. Striped patterns of gene expression that lead to the future body segments appear sim…
How Fast Elements can Affect Slow Dynamics
Koichi Fujimoto, Kunihiko Kaneko
A chain of coupled chaotic elements with different time scales is studied. In contrast with the adiabatic approximation, we find correlations between faster and slower elements whe…
