EVs from NFAT3-expressing cells can further increase their anti-tumor effects and are effective in inhibiting tumor growth on a pre-established cancer. (A) 5.105 MDA-MB-231 cells (D3H2LN-LUC) were injected into the left Fat Pad of each 6-weeks-old female Athymic Nude mouse. Tumor volume: Tumor growth is presented as the mean tumor volume (cm3) ±SEM, from mice injected weekly intra tumor with PBS or with EVs T-47D toCtl (5 × 109 pp) or EVs T-47D ΔNFAT3, 7 days after cell xenotransplantation, 10 mice per group. Metastases: Beginning day 35, weekly, bioluminescent images (where the primary tumor was shield with a black tissue) were acquired on the IVIS system to quantify the mean photon flux produced by the metastatic cells. Metastases quantification is presented as the mean photon flux produced by the metastatic cells. Data from one representative experiment of two independent experiments is shown, all data are shown as mean ± SEM (n = 10 technical replicates;, *p < 0.05 **p < 0.005 and ***p < 0.001 compared to PBS-injected mice; (**), (***) compared to EVs-T-47D toCtl-injected mice). (B). 105 MDA-MB-231 cells (D3H2LN-LUC) were injected into the left Fat Pad of each 6-weeks-old female Athymic Nude mouse. Tumor volume: Tumor growth is presented as the mean tumor volume (cm3) ±SEM, from mice injected weekly intra-tumor with PBS or with 5 × 109 pp EVs T-47D ΔNFAT3, 38 days after cell xenotransplantation, 10 mice in each group. Metastases: Beginning at day 45, weekly, bioluminescent images (where the primary tumor was shield with a black tissue) were acquired on the IVIS system to quantify the mean photon flux produced by the metastatic cells. Metastases quantification is presented as the mean photon flux produced by the metastatic cells. Data from one representative experiment of three independent experiments is shown, all data are shown as mean ± SEM (n = 10 technical replicates; ***p < 0.001, compared to the PBS treated mice group).
