Expression of ABCG2, ABCB1 and Nanog in the CD44⁺117⁺CSCs in 3D culture and 2D cultures. A-C indicate the expression of ABCG2, ABCB1 and Nanog in the CD44⁺117⁺CSCs and SKOV-3 cells respectively, as they were cultured in the 3D or 2D culture medium detected by qRT-PCR. Statistically significant differences are indicated by asterisk (*) for P <0.05, (**) for P < 0.03, (***) for P < 0.01. # indicates P > 0.05.
