Collective cell motion : a model and some experiments.
Vincent Hakim, Département de Physique - Ecole Normale Supérieure Laboratoire de Physique Statistique
In different biological processes, cells move in a coordinated way.
Several experiments have quantitatively investigated this phenomenon. We
will describe a simple model of interacting persistent random walkers that
we have developed to phenomenologically describe collective cell motion,
based on data obtained by the team of P Silberzan (Institut Curie, Paris).
The model helps to explain the observed motion of a confined cell
assembly which displays stochastic reversals of global rotational motion
and pulsatile collective modes. At a more general level,
this provides an example of a "mesoscopic"
statistical problem, with a number of particles between a few tens to
a few hundreds, which is not so often encountered in usual
condensed matter physics.
