Migration after Snail knockdown in ARPE19 cells with or without TGF-β1 treatment.

Abstract

<p>(A) Cells transfected with control-shRNA or Snail-shRNA were allowed to migrate transwell chambers for 18 hr in the presence or absence of TGF-β1. After 18 hr, the migrated cells were fixed, stained, and photographed. (B) The number of migrated cells. Data shown represent the average of three independent experiments. *P<0.05, compared with control-shRNA, TGF-β1(−) samples and control-shRNA, TGF-β1(+) samples.</p
