Figure 3. Detection of pathological changes in each group.
Pathological changes in the kidney tubules, kidney glomeruli, and collecting tubules were observed under a light microscope using H&E staining. Scale bar of the phase observed through H&E staining corresponds to 100 μm. Histological score of each group was also evaluated herein. Results are expressed as mean ± SEM. A t-test was used to compare the various groups. *P < 0.05 compared with the model group. #P < 0.05 compared with the normal UC-MSCs group and UC-MSCs-vector group respectively.
