VEGFA and neoplasm: A broad range of pro-angiogenic factors were detected in the PMP tumor samples; high levels were observed for some factors (VEGFA, PlGF, FGF2 and sflt1), moderately increased (VEGFC and VEGFD) or low levels (angiopoietin1 and Tie2) for others, compared to values measured in serum samples from healthy humans (Table 2a).
