a, Growth curve of C1-sgControl, C1-sgEED-Mes and
C1-sgKMT2D-Mes cells in vitro. n=3. *, p = 0.03; **, p =
0.005. n.s., not significant.. b, Quantification of mammosphere
formation by C1-sgControl, C1-sgEED-Mes and C1-sgKMT2D-Mes cells. n=3. ***,
p<0.001. c, Differences in primary tumor-initiating
ability of C1-sgControl, C1-sgEED-Mes and C1-sgKMT2D-Mes cells upon
transplantation with limiting dilution into NSG mice. Tumors that arose from
transplantation of 2 × 106 cells were of similar size. n=5
in each group. d,e, Representative bright-phase and
fluorescence microscopy (d) and number of metastatic nodules
(e) shows metastatic outgrowths in the lung of
C1-sgControl, C1-sgEED-Mes and C1-sgKMT2D-Mes cells 8 weeks after fat pad
implantation. n=5 in each group. ***, p<0.001. n.s., not significant.
Statistical analysis was performed using one-way ANOVA followed by Tukey
multiple-comparison analysis. Data are presented as mean ± SEM.
