(A) Frequency of LDN among CD45+ cells in the blood of healthy donors, ovarian cancer patients, and NSCLC patients. (B) Frequency of TAN among CD45+ cells within the tumor single-cell suspensions. (C) Frequency of LDN among myeloid (CD33+) cells and numbers of LDN in the blood. (D) Frequency of TAN among myeloid (CD33+) cells within the tumor single-cell suspensions. Statistical analyses: Wilcoxon–Mann–Whitney’s test. P-values: ns (non-significant), ≥ 0.05; **, <0.01; ***, <0.001; and ****, <0.0001.
