Characterization of Uptake Mechanism YSL-Exosomes by Endothelial Cells (A) Close up of the CVP area of 3 dpf Tg(kdrl:Hsa.HRAS-mCherry) zebrafish embryos expressing CD63-pHluorin in the YSL, treated with BafA to show internalized EVs and co-treated with DMSO (CTRL) or dynamin-inhibitor Pyrimidyn-7 (Pyrimidin-7). (B) Quantification of experiments as performed in (A), showing the overlap coefficient of red with green (M1) and green with red (M2) signal (mean ± SD, ∗∗∗∗p ≤ 0.0001; n ≥ 3; unpaired t test with equal SD). (C) As in (B), but for macrophages alone (mean ± SD, ∗∗∗∗p ≤ 0.0001; 7 macrophages per condition, n ≥ 3; unpaired t test with equal SD). (D) Close up of the CVP area of 3 dpf Tg(kdrl:Hsa.HRAS-mCherry) zebrafish embryos expressing CD63-pHluorin in the YSL treated with BafA to show internalized exosomes and non-injected or injected with 500K Dextran Sulfate (DS500K). (E) Quantification of experiments as performed in (D) (mean ± SD, ∗p ≤ 0.05; n ≥ 2; unpaired t test with equal SD). YSL, yolk syncytial layer; BafA, bafilomycin A; CVP, caudal vein plexus. Scale bars represent 10 μm. |
