Quantification of change in the microtubule array following cytochalasin D and ML-7 treatment

	MT length (μm)	MT number	(n)
Control	5.75  ± 0.08	22.14  ± 0.14	278
Cytochalasin D	11.67  ± 0.17	30.19  ± 0.28	171
ML-7	11.99  ± 0.16	30.62  ± 0.4	237

The MT array in PMNs was quantified by manually tracing the paths of anti-α-tubulin labeled filaments from confocal images. Data represent average number and length (μm) ± SEM of individual microtubules from 18 control, 11 cytochalasin D-treated (Fig. 4), and 11 ML-7-treated cells (Fig. 5) from two independent experiments. (n), the number of individual microtubules analyzed for each condition.
