Article Title: Targeting cancer-derived extracellular vesicles by combining CD147 inhibition with tissue factor pathway inhibitor for the management of urothelial cancer cells

doi: 10.1186/s12964-024-01508-x

Figure Lengend Snippet: Association of tissue factor (TF) and CD147 overexpression with extracellular vesicle (EV) production and invasion potential. The expression of green fluorescent protein (GFP)-fusion CD147 on the plasma membrane of J82 cells was observed using confocal microscopy ( A ). To assess the vesicular export of CD147, GFP-labeled vesicles were derived from J82 cells transfected with the CD147-GFP construct and analyzed using flow cytometry ( B ). The lysates of the EVs were prepared using 0.1% Triton™ X-100. EVs were derived from human bladder urothelial carcinoma J82 cells co-transfected with TF and CD147 plasmids. The EVs were quantified using NTA in the 48-h culture supernatant of J82 cells overexpressing CD147 and TF versus that of the control transfection condition ( C ). Invasion potency was measured by a Transwell assay, with 6–8 images of the cells that had passed through the coated microporous membrane after 24 h per experiment ( D )

Article Snippet: J82 cells were exposed to their own isolated and characterized microvesicle-like EVs, which were pre-incubated with or without the CD147 inhibitor AC-73 (MedChemExpress LLC, NJ), human recombinant TFPI together with factor VII (Sigma-Aldrich, MO), or human recombinant CD147 protein (rCD147, Sino Biological Europe, Germany) for the specified duration.
