Neuropilin 1 and neuropilin 2 co‐expression is significantly correlated with increased vascularity and poor prognosis in nonsmall cell lung carcinoma

The co-expression of NRP1 and NRP2 genes is significantly correlated with tumor progression through neovascularization in NSCLC. These results suggest that both NRP1 and NRP2 are key molecules for stromal vascularization by cell-retained VEGF in NSCLC.
