Vascular Endothelial Growth Factor Inhibits Phagocytosis of Apoptotic Cells by Airway Epithelial Cells

Figure 2

VEGF inhibition of phagocytosis was not associated with masking of PS on the apoptotic cell surface. AECs were inoculated into 12-well plates ( cells/well) and treated with curcumin for 72 h before incubation with PBS or 100 ng/ml, 500, or 1000 ng/ml VEGF for 6 h. After washing with PBS, the cell surface PS was assayed by flow cytometry. A representative flow cytometry assay is shown on the left and the figure on the right shows the assay results.
