Fig. 1: Transduction of MDA-MB-231 cells with Fluc/GFP and pStat3/Rluc reporter genes.

(a) Transduced MDA-MB-231 cells were strongly positive for eGFP as shown by fluorescence microscopy. (b) Ex vivo imaging analysis of stably transduced MDA-MB-231 cells showed a strong correlation between cell numbers and Fluc reporter gene activity. The scale bar represents 50 μm
