Monocyte phenotypic profiles.

Monocyte subset	Phenotype
Pre-classical monocyte	CD14⁺CD16^–CD45⁺CD69⁺MMP9⁺CCR2⁺CXCR4⁺
Classical monocyte	CD14⁺⁺CD16^– CD45⁺CD69⁺MMP9⁺CCR2⁺CXCR4⁺
Intermediate monocyte	CD14⁺⁺CD16⁺CD45⁺⁺CD69⁺MMP9⁺CCR2⁺CXCR4⁺
Non-classical monocyte	CD14⁺CD16⁺⁺CD45⁺⁺CD69⁺MMP9⁺CCR2⁺CXCR4⁺

A more accurate flow-cytometry characterization of monocyte subsets was performed in five patients presenting with NSTE-ACS, according to the expression of the following surface markers: CD14, CD16, CD45, CD69, MMP-9, CCR2, and CXCR4. See also Supplementary Figure 1.
