From: BlyS is up-regulated by hypoxia and promotes migration of human breast cancer cells
Migration of human breast cancer cells in the presence of BLyS. 0.1 ng/ml, 1 ng/ml and 10 ng/ml BLyS were added in the lower chamber. 2% FBS and 1% FBS added in the lower chamber were used as positive chemoattractant and negative chemoattractant respectively. (A) MDA-MB-435. (B) MDA-MB-231. (C) MDA-MB-468. Average numbers of cells migrating in five randomly selected fields were counted after 8 h (original magnification 200 ×). Data are means of triplicate samples with ± SD; *, P < 0.05, **, P < 0.01, ***, P < 0.001, vs 1% FBS under normoxia. #, P < 0.05, ##, P < 0.01, ###, P < 0.001, vs 1% FBS under hypoxia.
