Physiological differences between the three groups. a, b Body weight and blood glucose levels of rats were examined weekly. The day that STZ-induced diabetic rats were established was referred to as day 0 of the experiment. ADSCs were injected at the end of the second week. c, d Serological index. e H&E staining (the upper panel is 10X, and the lower panel is 40X). NC normal control group, STZ STZ-induced diabetic group, ADSC group ADSC-treated group. *p < 0.05 and **p < 0.01 versus the NC group, #p < 0.05 versus the STZ group
