WebIn light of these findings, the persistent random motion of cell migration has been questioned, and other more complicated theoretical models have been introduced [24, 27] to confront with experimental results. Therefore, the aim of the present work is to revisit the idea that single-cell motility can be described as a random walk. WebAbstract.
