Fig. 7

Representative IHC images of STEM121 levels at low magnification (a) and higher magnification (b) from three independent tumors from each of the vehicle control, pacritinib, selumetinib, and combination pacritinib + selumetinib treatment groups. Scale bars: 1500 μm (a) and 600 μm (b). c ImageJ quantification of UI226 tumor area from STEM121 stained slides representing the vehicle control (N = 4), pacritinib (N = 3), selumetinib (N = 4), and combination pacritinib + selumetinib (N = 4) treatment groups. Results were analyzed using ANOVA and a Dunnett’s test for multiple comparisons. Error bars: SEM. p < 0.05*. vehicle vs pac/sel, p = 0.0105. d Representative MRI images from three independent RCMB18 tumors representing the vehicle control, pacritinib, selumetinib, and combination pacritinib + selumetinib treatment groups. Arrows denote individual or multiple tumor lobes in representative images from each treatment group. e ImageJ quantification of RCMB18 tumor volume from compiled MRI images representing the vehicle control (N = 3), pacritinib (N = 3), selumetinib (N = 3), and combination pacritinib + selumetinib (N = 3) treatment groups. Results were analyzed using ANOVA and a Dunnett’s test for multiple comparisons. Error bars: SEM. p < 0.05*. vehicle vs pac/sel, p = 0.0308.
