The effects of MSC-CM on the cell viability, wound healing and cell migration of HUVECs in the control, HG and MSC-CM groups. A, B showed the fluorescence intensity and the representative pictures in the resazurin-based assay. C Cell viability detected by MTT method. D, E showed wound healing rate and representative pictures in the scratch test (scale bar = 50 μm). F, G showed the number of cell migration and the representative pictures in the transwell experiment, and each group randomly selected four fields for cell counting (scale bar = 50 μm). Data were mean ± SD, **P < 0.01 versus control level, #P < 0.05 and ##P < 0.01 versus model level
