CA and Tz cooperatively inhibit in vitro BT474 cell migration. Cells were cultured after 48 h of starvation for 7d with control medium (Ctr), CA, Tz or CA + Tz supplemented medium in the lower migration chamber, which was changed every other day. a Representative images of the lower side of the migration membranes stained with Crystal Violet. Bar = 100 μm. b Relative cell migration expressed as percentage (%) compared to Ctr cultures was determined as detailed in Methods section. Mean values and standard deviation (indicated as vertical bars) from four independent replicates (n = 4) are shown. P < 0.005 (*), P < 0.01 (**), P < 0.001 (***)
