(A)
FZD7 mRNA levels (mean fold-change ± SD, n=3–4)
in FZD7 (+) and FZD7 (−) cells FACS selected from SKOV3, OVCAR5, and
COV362 cells and HGSOC tumors. (B-D) Cell viability (mean
fold-change ± SD, n=4) of FZD7(+) and FZD7(−) cells from OVCAR5
(n=3) (B), SKOV3 (n=3) (C) or COV362 (n=4)
(D) cells, plated, treated with the indicated doses of CDDP for
24 hours, and cultured for additional three days. (E, F)
Representative pictures and numbers (mean ± SD, n = 4–5) of
spheroids formed after 7 days of culture by FZD7(+) and FZD7(−) cells
FACS sorted from SKOV3 (E) and OVCAR5 (F) OC cells.
Spheroids were counted or cell numbers were estimated by CellTiter-Glo 3D cell
viability assay. (G-I) mRNA levels (fold-change ± SD) of
Nanog in FZD7(+) compared with FZD7(−) cells from
SKOV3 (G) (n=3), OVCAR5 (H) (n=8) and COV362 (I)(n=3) cells. For all
comparisons: *P<0.05, **P<0.01, ***P<0.001.
