Cell migration assay.

<p>A. Assay of NIH3T3-mock and NIH3T3-flagOVA66 cell migration capacity by monolayer wound healing. Magnification: 100×. The relative scratch width(%) means the width at 24 hr/the width at 0 hr. The data represent mean ± SEM (n = 3), **<i>P</i>≤0.01 B. Assay of transfected NIH3T3 cell migration capacity by transwell migration assay <i>in vitro</i>. The polycarbonate were stained with Crystal violet and inspected under a microscope at 200×. The Column means the number of cells that migrated the Transwell membranes, the data are represented as mean ± SEM, **<i>P</i>≤0.01.
