In congruence with the findings on mouse T241 tumors expressing NRP1 or not on tumor cells (Figure 1), the presence of VEGFR2/NRP1 trans‐complexes in PDAC correlated with reduced vascular area, vessel count, vessel branching, and tumor proliferation (Figure 4F–J), while the individual vessel area was not affected (Figure 4H). This evidence concerns the gene KDR and neoplasm.
