Fig. 4: Proliferation and transformation activity of FGFR2 fusions.

Representative images of colonies expressing different FGFR2 fusions in NIH3T3 cells are shown (a). Average colonies with different FGFR2 fusions are plotted (b). Representative images of transwell migration expressing different FGFR2 fusions in RBE cells are shown (scale bar = 100 μm) (c). Average numbers of migrated cells with FGFR2 fusions are plotted (d). Ba/F3 cell growth curve with (e) or without IL3 (f) are shown. *p < 0.05, **p < 0.01.
