Breakdown of Rheological Universality in the Vegetal Hemisphere of Ascidian Embryos Mapped by Atomic Force Microscopy

Yuki Miyata, Miki L. Yamamoto, Takahiro Kotani, Yosuke Tsuboyama, Takaharu Okajima

The paper uses AFM to show that vegetal hemisphere cells in ascidian embryos exhibit diverse rheological properties, unlike the uniform behavior of animal hemisphere cells.

Mapping single-cell mechanics in the early embryogenesis of Xenopus laevis using atomic force microscopy

Miki L. Yamamoto, Takayoshi Yamamoto, Takahiro Kotani, Yuki Miyata, Tatsuo Michiue, Takaharu Okajima

This study uses atomic force microscopy to map single-cell stiffness in Xenopus laevis embryos, revealing mechanical differences between animal and vegetal hemispheres during early development.
