Flow cytometric analysis showing the expression of CD14, CD11c, and CD45 markers in ODN treated HL60 cells before and after 48 hours of PMA induction. Peak 1 represents the expression of the adhesion molecule CD11c; peak 2 shows the level of expression of the CD14 antigen and peak 3 of CD45 antigen. The expression of the above listed markers has been evaluated in HL60 cells treated with the mixture of hFES-IP-sj1 and 2 (A); in HL60 cells treated with the mixture of hFES-AS-sj1 and 2 (B); in HL60 cells treated as described in (A) and induced to macrophage differentiation in the presence of control ODN (C); in HL60 cells treated as described in (B) and induced to macrophage differentiation (D).
