<p>A. Structures of migracin A and B. B. Effect of migracin A on the viability of ES-2 cells. The cells were incubated with migracin A for 24 h, and viability was assessed by MTT. C. Inhibition of cellular migration. Migration was measured by wound healing assay. The cells were incubated for 24 h. D. Inhibition of cellular invasion. Invasion was measured by Matrigel chamber assay. The cells were incubated for 24 h. *, P<0.05. **, P<0.01 (n = 3).</p
