Tumorigenicity and Validity of Fluorescence Labelled Mesenchymal and Epithelial Human Oral Cancer Cell Lines in Nude Mice
(a) Cryosection of a UM1-GFP tumor. The tumor presents a disorganized cell pattern (A) (magnification 40x) with an aggressive invasion front (B) (magnification 20x). (b) Cryosection of a UM2-RFP tumor. A clear border (B) (magnification 20x) between well-defined tumor cells (A) (magnification 40x) and the surrounding can be detected.
