Figure 2.

Chemotactic index, velocity, and speed of cPMNs and oPMNs in response to fMLP or PBS. Quantitative analysis of migration is presented in Tukey box and whiskers plots. The box represents the 75 and 25th percentiles with the median presented as a midline. Tukey whiskers represent the minimum and maximum values and outliers were defined as values exceeding 1.5 times the interquartile range. The chemotactic index, which is the directional accuracy of chemotaxis, is presented in (A). The cell velocity, representing the average speed (μmeter/min) of the cells moving in its most prominent direction, is presented in (B). The speed, which is the average speed (μmeter/ min) moving in any direction is presented in (C). n = 9, ^**p < 0.01, ^***p < 0.001.
