Furthermore, the extent of NG2+ pericyte coverage of tumor microvessels (RIP1-Tag2: 94.3% ± 0.87% vs RIP1-Tag2; RIP1-VEGFB: 94.3% ± 0.62% of all vessels were covered with NG2), as well as the functionality of the vasculature, as quantified by perfusion with fluorescein-labeled tomato lectin (RIP1-Tag2: 93.1% ± 1.4% vs RIP1-Tag2; RIP1-VEGFB: 93.5% ± 1.4% of all vessels were lectin perfused), remained unaffected by the expression of VEGF-B (Figure 3c). Here, VEGFB is linked to neoplasm.
