Cell orientation dynamics in the absence of chemoattractant. (a,b) Distribution of step angles over 10 minutes (a) or 120 minutes (b). The distributions are skewed to 0° (direction away from the well), especially at the beginning of the assay. (c–f) Distribution of step angles differences after an initial forward step (c–e), or backward step (f) for delay times of 10 seconds, 1 minute and 10 minutes, respectively. The results are representative for 8 independent experiments.
