Current Status of Lymphangiogenesis: Molecular Mechanism, Immune Tolerance, and Application Prospect
The lymphatic system is a channel for fluid transport and cell migration, but it has always been controversial in promoting and suppressing cancer. VEGFC/VEGFR3 signaling has long been recognized as a major molecular driver of lymphangiogen…
