VEGFA and posterior cortical atrophy: Because the highest concentration of VEGF-C in the conditioned medium of PC3 cells is unable to elicit LEC transmigration in our model, and the anti-VEGF-A completely abolished the difference of migration between conditioned media of Cav-1-expressing and -down-regulated cells, we suggest that the effect of PCa Cav-1 on lymphangiogenesis is mediated by the panangiogenic factor VEGF-A.
