Figure 4From: Cancer-associated fibroblasts provide a suitable microenvironment for tumor development and progression in oral tongue squamous cancerTca8113 and CAL-27 in CAFs CM grow faster than in NFs CM. XTT assay was used to compare cell growth rates between Tca8113or CAL-27 in CAFs and NFs CM (a, b). Two examples of DNA content comparison between Tca8113 and CAL-27 in CAFs CM, NFs CM and its own CM by flow cytometry. Flow cytometry histogram shows that the percentages of cells in S and G2-M phases were significantly higher in CAFs CM compared with NFs and its own CM (c, d).Back to article page
