Figure 1. The CSCs characteristics of tumorsphere cells.
(A) Tumorspheres formed after 14 days. (B) The sub-tumorspheres formation ability of tumorsphere cells (white bars) and adherent cells (black bars). * = P<0.05. Bars = 1000µm. (C) The colonies formation ability of tumorsphere cells (white bars) and adherent cells (black bars) under anchorage-independent conditions by soft agar assays. * = P<0.05. (D) Effect of 48 hours exposure of tumorsphere cells (white bars) and adherent cells (black bars) to 1000 µM chemotherapeutic drug. Ox = oxaliplatin, Mi = mitomysin. * = P<0.05.
