For biophysical understanding of cell motility, the relationship between mechanical force and
cell migration must be uncovered, but it remains elusive. Since cells migrate at small scale …

In early embryos, microtubules form star-shaped aster structures that can measure up to
hundreds of micrometres in size, and move at high speeds to find the geometrical centre of the …

Although mechanisms that contribute to microtubule (MT) aster positioning have been extensively
studied, still little is known on how asters move inside cells to faithfully target a cellular …

Neisseria meningitidis, a bacterium responsible for meningitis and septicemia, proliferates
and eventually fills the lumen of blood capillaries with multicellular aggregates. The impact of …

We report a quantitative measurement of traction stress exerted by dividing eukaryotic cells.
The stress field was highly dynamic and sequentially changed as follows:(1) strong and …

How growing cells cope with size expansion while ensuring mechanical integrity is not
known. In walled cells, such as those of microbes and plants, growth and viability are both …

The spatial gradient of signaling molecules is pivotal for establishing developmental patterns
of multicellular organisms. It has long been proposed that these gradients could arise from …

Walled cells of plants, fungi, and bacteria come with a large range of shapes and sizes, which
are ultimately dictated by the mechanics of their cell wall. This stiff and thin polymeric layer …

Intracellular structures and organelles such as the nucleus, the centrosome, or the mitotic
spindle typically scale their size to cell size [1]. Similarly, cortical polarity domains built around …

We consider random walks of active deformable particles (ADP) that can move by actively
deforming their shape from a sphere. A theory is developed by assuming that the equation of …
