Subcellular lateral distribution of vesicles in the subcellular zones. The total number per cell for each vesicle type was considered as 100%. Values are presented as mean, n > 9. Statistical analysis; Difference was analysed by one-way ANOVA followed by Tukey’s posthoc test. Values were considered statistically significant at *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001 between the cell lines (bEnd.3 vs. hCMEC/D3) and at ^#p ≤ 0.05, ^##p ≤ 0.01, ^###p ≤ 0.001 compared to the primary PBEC
