Sphere cells exhibited properties of myeloid progenitors (inflammation/myeloid, group 2). A: Cell surface expression of determinant myeloid cell markers CD14 and CD115 (CSF-1R) by monolayer and sphere cell populations. Data shown are representative of three experiments. B: Phagocytosis of fluorescein isothiocyanate–conjugated, IgG-coated latex beads by monolayer and sphere cells. Phagocytosis is represented as relative fluorescence intensity by each cell line. The macrophage cell line RAW246.7 was used as a positive control. Data shown are means ± SD representative of at least two independent experiments. The increased phagocytic activity in the SB and Dal-4 sphere cells was significant compared with the activity detected in monolayer cells.？P ≤ 0.05
