Pulsed Electromagnetic Field Inhibits Synovitis via Enhancing the Efferocytosis of Macrophages

Figure 1

PEMF alleviates the degree of synovitis in the DMM model. (a) The procedure of mice treated with PEMF after DMM: 24 mice were randomly divided into three groups and used for the experiment. After DMM surgery, one group of mice was treated with PEMF. After two weeks, all mice were sacrificed and the medial compartment of the knee was histologically evaluated. (b) PEMF device and parameters used. (c) Histological evaluation: representative images of the medial compartment of the knee were showed. Scale bar: 200 μm. (d) Synovitis score of each group was calculated. Statistical analysis was performed by one-way ANOVA, and multiple comparisons were performed using Tukey’s test. Error bars represent the of eight independent experiments. , .
