In this paper a measure is proposed of the rate with which the collective motion of cells leads to aggregation and structure formation. It will be shown that the spatial entropy of the cells tends to decrease during aggregation and an index will be derived to quantify the rate with which this...

Despite spectacular progress in biophysics, molecular biology and biochemistry our ability to predict the dynamic behavior of multicellular systems under different conditions is very limited. An important reason for this is that still not enough is known about how cells change their physical and...
