Immature myeloid cells in peripheral blood.

<p>Panel A (upper left): a typical example of gating of low, intermediate (Int.) and high complexity sets among CD33⁺ cells in flow cytometry. Panel B (upper right): low, intermediate and high complexity CD33⁺ cells were analysed on the basis of CD14 and HLA-DR expression. A typical example is shown in this panel. Panel C (lower left): Blood low complexity CD33⁺CD14⁻HLA-DR⁺ cells. Panel D (lower right): blood low complexity CD33⁺CD14⁻HLA-DR⁻ cells. Ref. = reference group made of patients with chronic pancreatitis (open dots) and of patients with splenic non-neoplastic lesions; BPNs = Borderline pancreatic neoplasms; PDAC = Ductal adenocarcinoma; NETs = Neuroendocrine tumors. * = p<0.004 (adjusted p-value for significance) with respect to Reference.
