a PKH26-labeled EVs were co-cultured with HUVECs for 6 h. Endocytosed EVs (PKH26, red) can be seen within the cytoplasm of HUVECs (CD31, green). Scale bar = 5 μm. b Tube formation experiments of HUVECs treated with different EVs. Scale bar = 150 μm. c–e Quantitative analysis of tube formation experiments (n = 5 independent experiments). ***p < 0.001 vs. Ctl, ***p < 0.001 vs. Neo-EVs. f Scratch migration experiments of HUVECs treated with different EVs. Scale bar = 150 μm. g Quantitative analysis of scratch migration experiments (n = 5 independent experiments). ***p < 0.001 vs. Ctl, ***p < 0.001 vs. Neo-EVs. One-way ANOVA followed by Tukey’s Multiple Comparisons test (c–e). Two-way ANOVA followed by Tukey’s Multiple Comparisons test (g). Error bars represent the mean ± SEM of each group.
