have found that bladder cancer cells secrete EVs with a lncRNA LN metastasis‐associated transcript 2 (LNMAT2), that induces LEC tube formation and migration in vitro, and promotes tumour lymphangiogenesis and LN metastasis in vivo in a vascular endothelial growth factor C (VEGF‐C)‐independent manner (Chen et al., 2020). Here, VEGFC is linked to urinary bladder carcinoma.
