Immunofluorescence staining for CD31 to identify angiogenesis in the cartilage of ACLT-induced mouse by a fluorescence microscope (OLYMPUS) (scale bar: 20 μm). A CD31-positive staining in the cartilage of the sham operation group and the model group. B CD31-positive staining in the blank group. C Blood vessel count in each group. The data in the figures represent mean values ± SD, *p < 0.05, **p < 0.01 compared with the control group, #P < 0.05, ##P < 0.01 compared with the sham group at the same point
