Identification and In Vivo Visualization of EVs in Zebrafish (A) Electron microscopic analysis of a 3 dpf zebrafish embryo showing heterogeneous EVs between basal epidermal cells. White arrows indicate exosome-like vesicles, and black arrow indicates an enwrapped cluster of vesicles. (B) Electron microscopy observation of EVs purified by ultra-centrifugation from the supernatant of AB.9 caudal fibroblastcells. (C) Mass spectrometry analysis of AB.9-derived EVs (excerpt, complete list in Table S1). (D) Transient mosaic expression of ubi:CD63-pHluorin in 35 hpf zebrafish embryo, pseudo-colored for depth. (E) Example of cell types in caudal fin targeted by transient mosaic expression of CD63-pHluorin (3 dpf). Identified as, among others, skin epithelial (SE), neuronal (N), and fibroblast cells (FC). Arrows point at labeled EV. (F) Example of a fusion event observed in a fibroblast-like cell (1), with zoom in (2), and time-lapse heatmap of the event (3). |
