A total of 18 invadopodia-related proteins were identified as sEV surface components, including adhesion molecules that may interact with receptors on target GBM cells (ITGA1, ITGA3, ICAM1) and proteolytic proteins (BSG, MMP14) that may activate extracellular MMP-2 to promote ECM degradation (Fig. 3E). This evidence concerns the gene ITGA3 and glioblastoma.
