Histogram and pictures of unstained cancer cells and stained CAFs. A. Representative histogram and sorting gates of unstained cancer cells and CMTMR-stained carcinoma-associated fibroblasts (CAFs) grown as the co-culture for 72 hrs. B. Histogram of cancer cells sorted from co-culture showing only CMTMR-negative cells. C. Histogram of CAFs sorted from co-culture showing only CMTMR-positive cells. D. and E. Representative pictures obtained using confocal microscopy showing red-colored stained cytoplasm (CMTMR staining) of CAFs growing as a single culture for 1 hr and 72 hrs, respectively. The imaging of cells was performed on confocal laser scanning microscope FV-500 system (Olympus Optical Co, Germany). The cells were examined using the Fluoview program (Olympus Optical Co., Germany). F. The graph showing mean optical density of the red (reflecting CMTMR staining) in CAFs at 1 hr and 72 hrs after staining. For statistical purposes the t-test has been applied (Graph Pad 5.0), no significant difference has been observed between these two values.
