abstract = {Proper functioning of white blood cells is not possible
without their ability to adhere to vascular endothelium,
which may occur only if they are close enough to vessel
walls. To facilitate the adhesion, white blood cells migrate
toward the vessel walls in blood flow through a process
called margination. The margination of white cells depends
on a number of conditions including local hematocrit, flow
rate, red blood cell aggregation, and the deformability of
both red and white cells. To better understand the
margination process of white blood cells, we employ
mesoscopic hydrodynamic simulations of a three-dimensional
model of blood flow, which has been previously shown to
capture quantitatively realistic blood flow properties and
rheology. The margination properties of white blood cells
are studied for a wide range of hematocrit values and flow
conditions. Efficient white blood cell margination is found
in an intermediate range of hematocrit values of Ht ≈
0.2–0.4 and at relatively low flow rates, characteristic
of the venular part of microcirculation. In addition,
aggregation interactions between red blood cells lead to
enhanced white-blood-cell margination. This simulation study
provides a quantitative description of the margination of
white blood cells, and is also highly relevant for the
margination of particles or cells of similar size such as
circulating tumor cells.},
