CD34 and neoplasm: Analysis for molecular expression profile showed higher expression of nearly all cell adhesion molecules (CAMs) (Siglec‐1, IL‐3R, PD‐1, CD14, CD86, PD‐L1, ICAM‐1, CD64, CD34, and CD206) on classical monocytes of responders compared to non‐responders, indicating a tumor‐infiltrating phenotype of these cells.
