B. Left: representative confocal images of mammary tumor formed by the co-injection of T47DDsRed reporter cells with either MDA-MB-231CFP;Cre;Control or MDA-MB-231CFP;Cre;HA-RASSF1C. Scale 200 μm. Right: averaged values for all mice for the percent of the eGFP+ or CFP+ cells as part of the whole tumor. Data information: All data are from n=3 independent experiments. Data are analyzed by Student T-test and represented as mean ± SEM.* p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001.
