Fig. 2. EWS cell migration after exposure to IGF2BP3pos or IGF2BP3neg EVs.
EWS IGF2BP3 positive parental cells (on the left) or IGF2BP3-silenced cells (on the right) were used as recipient cells. Data from three independent experiments of cells receiving IGF2BP3pos or IGF2BP3neg EVs are shown. a Migration of A673 parental cells after exposure to its own EVs (CTR), or shNC EVs versus IGF2BP3neg EVs extracted from A673#18 or #54. Histograms represent the ratio ± SE of migrated cells compared to CTR. *p < 0.05, One-way ANOVA with respect to CTR. b Migration of IGF2BP3-silenced A673#18 cells after exposure to its own EVs (CTR) versus IGF2BP3pos EVs extracted from the parental A673 cells. Histograms represent the ratio ± SE of migrated cells compared to CTR. *p < 0.05, Student t-test. c Migration of TC-71 parental cells after exposure to its own EVs (CTR), or shNC EVs versus IGF2BP3neg EVs extracted from TC-71#46 or #73 cells. Histograms represent the ratio ± SE of migrated cells compared to CTR. **p < 0.01,***p < 0.001, One-way ANOVA with respect to CTR. d Migration of IGF2BP3-silenced cell line TC-71#46 after exposure to its own EVs (CTR) versus IGF2BP3pos EVs extracted from the parental TC-71 cells. Histograms represent the ratio ± SE of migrated cells compared to CTR. *p < 0.05, Student t-test. e Migration of TC-71 parental cells after exposure to IGF2BP3pos EVs extracted from EW#5-C cells versus IGF2BP3neg EVs extracted from EW#5-C sg-IGF2BP3-1 cells. Histograms represent the ratio ± SE of migrated cells compared to TC-71 treated with EW#5-C EVs. **p < 0.01, Student t-test. f Migration of IGF2BP3-silenced cell line TC-71#46 after exposure to IGF2BP3neg EVs extracted from EW#5-C sg-IGF2BP3-1 versus IGF2BP3pos EVs extracted from parental EW#5-C. Histograms represent the ratio ± SE of migrated cells compared to TC-71#46 cells treated with sg-IGF2BP3-1. **p < 0.01, Student t-test.
