Enrichment and characterization of cell line and tissue explant EVs. a) Surgical resections of healthy FT or tumor tissues were minced and used to initiate short-term tissue explants (cultured for 24 h) followed by collection of the conditioned media and processed by differential ultracentrifugation to enrich for EVs. Likewise, conditioned media from the FT and ovarian cancer cell lines shown was collected and processed. Created with BioRender.com b) Representative NTA data. c) Sixty (60) EV particles were imaged, and their size was measured for representative samples by TEM at x30K magnification. d) Shown are representative SP-IRIS and fluorescence (ExoView) data of FT tissue explant derived EVs displaying the common tetraspanins observed with cell-line derived EVs: CD9 (blue), CD63 (pink) and CD81 (green).
