Interaction of YSL-Exosomes with Endothelium and Presence of YSL-Exosomes in ISF (A) Time-lapse of Video S5A, showing the rolling and arrest of exosomes in the cardinal vein of 3 dpf zebrafish embryo expressing CD63-pHluorin in the YSL. (B) Quantification of dwelling time of CD63-pHluorin exosomes at the vascular wall (mean ± SD, n = 20 events). (C) EM image of the CVP of a 3 dpf zebrafish embryo expressing CD63-pHluorin in the YSL, labeled with gold particles directed to GFP (10 nm). Insert indicates area shown at higher magnification to the right. Arrow indicates internalized CD63-pHluorin exosomes in endo-lysosomal compartment of endothelial cell. (D) Close up of the cardinal vein of 3 dpf Tg(kdrl:Hsa.HRAS-mCherry) zebrafish embryos expressing CD63-pHluorin in the YSL, control-treated (DMSO), or treated with bafilomcinA (BafA) to neutralize acidic compartments. (E) CVP area of 3 dpf Tg(kdrl:Hsa.HRAS-mCherry) zebrafish embryos sham-injected or injected with CD63-pHluorin pDNA in the YSL. (F) Mid-trunk segment of 3 dpf zebrafish embryos expressing CD63-pHluorin in the YSL and mCherry under the ubiquitous RPL5 promoter. At this exposure level in the red channel, mostly muscle cells are visible. YSL, yolk syncytial layer; CVP, caudal vein plexus; PCV, posterior cardinal vein. |
