The study of vesicles under flow, a model system for red blood cells (RBCs), is an essential
step in understanding various intricate dynamics exhibited by RBCs in vivo and in vitro. …

Soft bodies flowing in a channel often exhibit parachutelike shapes usually attributed to an
increase of hydrodynamic constraint (viscous stress and/or confinement). We show that the …

Vesicles are locally-inextensible fluid membranes, capsules are endowed with in-plane shear
elasticity mimicking the cytoskeleton of red blood cells (RBCs), but are extensible, while …

The unique ability of a red blood cell to flow through extremely small microcapillaries depends
on the viscoelastic properties of its membrane. Here, we study in vitro the response time …

Mammalian cells developed two main migration modes. The slow mesenchymatous mode,
like crawling of fibroblasts, relies on maturation of adhesion complexes and actin fiber traction…

The dynamics of vesicles under shear flow are carefully analyzed in the regime of a small
vesicle excess area relative to a sphere. This regime corresponds to the quasispherical limit, …

Many eukaryotic cells undergo frequent shape changes (described as amoeboid motion) that
enable them to move forward. We investigate the effect of confinement on a minimal model …

Microorganisms, such as bacteria, algae, or spermatozoa, are able to propel themselves
forward thanks to flagella or cilia activity. By contrast, other organisms employ pronounced …

Vesicles are becoming a quite popular model for the study of red blood cells. This is a free
boundary problem which is rather difficult to handle theoretically. Quantitative computational …

Blood flow shows nontrivial spatiotemporal organization of the suspended entities under the
action of a complex cross-streamline migration, that renders understanding of blood …
