Evaluation of the phenotype and function of ASCs isolated from diabetic, old, and young patients. a EdU assay analysis of the proliferation rate of ASCs from those three groups. The proliferative cells and cellular nuclei were stained with green and blue colors. Scale bar 50 μm. c Images of migratory ASCs from those three groups. Scale bar 50 μm. e β-gal Staining assay analysis of the senescent rate of ASCs from those three groups. The senescent cells were stained with the blue color. Scale bar 50 μm. g Images of tube formations in HUVECs treated with conditioned media of ASCs from those three groups. Scale bar 50 μm. i Images of migratory fibroblasts given above treatments. Scale bar 100 μm. b, d, f, h, and j Qualified data shown in a, c, e, g, and i separately. N = 5. *p< 0.05, **p< 0.01, ***p< 0.001, ****p< 0.0001
