The cortex is a thin, crosslinked actin network lying immediately beneath the plasma membrane
of animal cells. Myosin motors exert contractile forces in the meshwork. Because the …

… (g) A virtual work differential for vertex displacement, depending on changes in cell volume
δV α , surface area δA k and edge length δl λ . External forces acting on vertices Inline …

We review the general hydrodynamic theory of active soft materials that is motivated in
particular by biological matter. We present basic concepts of irreversible thermodynamics of …

Differential cell adhesion and cortex tension are thought to drive cell sorting by controlling
cell-cell contact formation. Here, we show that cell adhesion and cortex tension have different …

Blebs are spherical membrane protrusions often observed during cell migration, cell spreading,
cytokinesis, and apoptosis, both in cultured cells and in vivo. Bleb expansion is thought …

Animal cell shape is largely determined by the cortex, a thin actin network underlying the
plasma membrane in which myosin-driven stresses generate contractile tension. Tension …

Contractile actomyosin rings drive various fundamental morphogenetic processes ranging
from cytokinesis to wound healing. Actomyosin rings are generally thought to function by …

… For MRLC–GFP, a stable cell line was created by transient transfection of WT cells followed
by selection with 500 μg ml −1 G-418 and clonal separation by FACS (performed at the …

… (F, G) Cellular contributions to wing blade area change in a dumpyov1 mutant wing.
Cumulative plots (G) were generated starting at 16.5 hAPF, the earliest time common to all …

Cytokinesis, the physical separation of daughter cells at the end of mitosis, requires precise
regulation of the mechanical properties of the cell periphery 1 , 2 . Although studies of …
