Pulsed Electromagnetic Field Inhibits Synovitis via Enhancing the Efferocytosis of Macrophages

Figure 4

The efferocytosis in macrophages is increased by PEMF treatment. (a) The procedure of efferocytosis: neutrophils were isolated from the bone marrow and cultured for 24 hours after CFDA labelling to induce apoptosis. The RAW264.7 cells treated with PEMF for 1 hour were 1 : 1 cocultured with apoptotic neutrophils for 4 hours. The efferocytosis rate was measured by flow cytometry. (b) Neutrophil purity was detected by immunofluorescence after isolation of mouse bone marrow neutrophils. (c) A confocal microscope was used to observe the efferocytosis. (d) The percentage of efferocytosis was measured by flow cytometry. Statistical analysis was performed by test. Error bars represent the of three independent experiments. .
