Non-monotonic fluidization generated by fluctuating edge tensions in confluent tissues
Takaki Yamamoto, Daniel M. Sussman, Tatsuo Shibata +1
In development and homeostasis, multi-cellular systems exhibit spatial and temporal heterogeneity in their biochemical and mechanical properties. Nevertheless, it remains unclear h…

Collective cell migration of epithelial cells driven by chiral torque generation
Takaki Yamamoto, Tetsuya Hiraiwa, Tatsuo Shibata
Various multicellular tissues show chiral morphology. Experimental studies have shown this can originate from cell chirality. However, no theory has been proposed to connect the ce…

Chirality-induced helical self-propulsion of cholesteric liquid crystal droplets
Takaki Yamamoto, Masaki Sano
We report the first experimental realization of a chiral artificial microswimmer exhibiting the helical motion. We found that a cholesteric liquid crystal droplet with a helical di…
