Figure 6. Effect of EVs secreted by MDA-MB-468 mammospheres on MCF7 cells.

Figure 6

(A) MCF-7 cells were incubated with 0, 25 and 50 µg/mL of MDA-MB-468 EVs and the number of mammospheres formed after 7-days was counted [data are mean ±SD; n = 3, *p<0.05, **p<0.01, relative to the values in the control]. (B) Quantitative polymerase chain reaction analysis was conducted to examine the expression of the factors Zeb1 and Snaill [data are mean ±SD; n = 3, p<0.05 and 0.05 respectively, relative to the values in the control].
