SDF-1α-induced VEGF production by peritoneal macrophages. A: CXCR4 expression on F4/80-positive murine peritoneal macrophages was determined by a flow cytometric analysis. Purified mononuclear cells were stained with rat anti-mouse F4/80 mAb and rabbit anti-CXCR4 Abs (filled histogram) or rat anti-mouse F4/80 mAb and non-immunized rabbit IgG (open heavy-lined histogram) as a control followed by staining with FITC-conjugated goat anti-rabbit IgG and PE-conjugated swine anti-rat IgG. A representative result from three independent experiments is shown. B: Peritoneal macrophages from WT mice were incubated with the indicated concentrations of SDF-1α for 12 h. Quantitative RT–PCR was performed on total RNAs extracted from the macrophages as described in Methods. Representative results from 3 independent experiments are shown here. C: VEGF mRNA levels were determined and normalized to Actb mRNA levels. Each value represents the mean and SEM (n=3). #, p<0.01 compared with untreated. D: VEGF protein expression was detected by immunocytochemical analysis using anti-VEGF Abs as described in Methods. Representative results from three independent experiments are shown.
