Differentiation of M1 cells to phagocytic cells induced by IL-6. (A) Uninduced parental M1 cells, which are blast-like cells. (B) M1 cells were induced to differentiate to phagocytic cells (macrophages) by culturing the cells at an initial concentration of 2 × 105 cells/mL for up to 2 days in the presence of 50 ng/mL IL-6. These cells represent phagocytized latex beads.
