Figure Lengend Snippet: HAMVEC were incubated for 24 hours with either EV-C, EV-PIC or were left untreated. Following treatment, cells were labeled with calcein, seeded in growth factor reduced matrigel coated plates and incubated for 6 hours before imaging. Representative micrographs (top panels) showing reduced formation of branches and reduced tubule length in HAMVEC treated with EV-PIC compared to untreated cells; Magnification 40x (Scale Bar=200-μm). Treatment with EV-PIC severely impaired tube network parameters compared to untreated control cells and EV-C treated cells. Angiogenesis was quantified in three independent experiments performed in triplicate. Three different pictures for each replicate were analyzed using the Image J Angiogenesis Analyzer software and data was represented as average ±SD. B: Oxygen consumption rate (OCR) was utilized to assess endothelial metabolism in cells treated with EV-C or EV-PIC using a Mitochondrial Stress Test. Cells were seeded into Seahorse XFe24 plates and allowed to attach and grow for 24 hours until they reached 70–80% confluence . Respiration data was normalized to total cellular protein. B: Proton efflux rate due to glycolysis (GlycoPER) was measured using the glycolysis stress kit in cells seeded in similar conditions as above. Data is normalized to total protein. C: Fatty acid oxidation was measured using palmitate-BSA as a substrate according to a protocol detailed in Methods section. For this assays cells were allowed to reach 100% confluence. Etomoxir (Eto) (4uM) was used as a positive control for inhibition of beta-oxidation Data represents average of three independent experiments performed in duplicate on cells from 3 individual donors on passages 4–6 and are expressed as the mean+/−SD.
