NRP1 and neoplasm: 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).
