VASH1 and cervical squamous cell carcinoma: identify that cervical squamous cell carcinoma-secreted exosomal miR-221-3p promotes lymphangiogenesis and lymphatic metastasis by targeting vasohibin-1-secreted exosomal miR-221-3p transfers into lymphatic endothelial cells to promote lymphangiogenesis and lymphatic metastasis via downregulation of VASH1 (83).
