Abstract: | Oral squamous cell carcinoma (OSCC) LN1-l cells previously showed greater capacities for lymphangiogenesis and lymph node metastasis compared to their parental OEC-M1 cells, in addition to an ability to enhance the migration and tube formation of lymphatic endothelial cells (LECs). Purified by a series of differential centrifugations and characterized using electron microscopy, dynamic light scattering, and western blot, LN1-1 cell-derived extracellular vesicles (LN1-1 EVs) were shown to promote LEC migration, tube formation, and uptake by LECs more effectively than did OEC-M1 cell-derived EVs (OEC-M1 EVs). Using stable isotope labeling with amino acids in cell culture/liquid chromatography-tandem mass spectrometry based proteomic platform, the laminin-332 proteins, including laminin alpha3, beta3, and gamma2, were validated as highly expressed proteins in LN1-1 EVs. Clinically, a higher level of laminin-332 was detected in plasma EVs from OSCC patients with lymph node metastasis than in both healthy controls and OSCC patients without lymphatic metastasis, suggesting EV-borne laminin-332 as a novel and non-invasive biomarker for the detection of lymph node metastasis in OSCC. The knockdown of laminin gamma2 and inhibition by anti-laminin-332 neutralizing antibodies impaired LN1-1 EV-mediated LEC migration, tube formation, and uptake by LECs. Importantly, laminin gamma2-deficient EVs showed a reduced ability to drain into lymph nodes in comparison with the control EVs. Additionally, the laminin 332/gamma2-mediated EV uptake was dependent on integrin alpha3 but not beta1, beta4 or alpha6. Collectively, the uptake of laminin gamma2-enriched EVs by LECs enhanced in vitro lymphangiogenesis and EV-borne laminin-332 is thus a viable biomarker for OSCC.
