Figure 2. Cell persistence is correlated with Diffusion Coefficient D.

Figure 2

All variables are plotted as a function of Inline graphic which is obtained (as well as the persistence time Inline graphic) by fitting Inline graphic with the Fürth's formula at long times (Inline graphic). (A) Persistence time Inline graphic (values larger than the time interval of 30 sec were considered); (BCD) Parameters obtained from a bimodal analysis; (B) Ratio of time spent in persistent mode over total tracking time; (C) Length of persistence Inline graphic (distance end-to-end of each individual persistent portion of cell trajectory); (D) cumulative Inline graphic, summed over all cell trajectory. Squares correspond to ‘Aging’ experiments, circles to Flow experiments. Inline graphic denotes averaging over all tracked cells in a given condition. Error bars represents SEM. The solid line in (A) is a linear fit Inline graphic (Inline graphic, Inline graphic).
