Furthermore, the presence of the pro-inflammatory protein Fibronectin, the putative cancer stem cell marker Prominin-1 (CD133), the tumor cell-derived collagenase stimulatory factor Basigin (CD147) and the immunosuppressive molecule B7-H3 (CD276) was confirmed by flow cytometric analysis of exosome-coated beads (Fig. 4). This evidence concerns the gene FN1 and cancer.
