Correlation between angiogenesis-associated molecules in the serum and cellular components in the peripheral blood of cancer patients. a Correlation between percentage of CD123⁺ DC2 and plasminogen activator inhibitor-1 (PAI-1). A moderate positive correlation was found (R = 0.50). b and c Correlation between immature myeloid cells and VEGF levels in the serum. A weak positive correlation was found to exist between the percentage of immature myeloid cells and VEGF levels (R = 0.35), and a stronger positive correlation was found between the absolute number of immature myeloid cells/microliter/blood and VEGF levels (R = 0.52)
