Temporal expressions of 8-hydroxy-20-deoxyguanosine (8OHdG) immunoreactivity in the bladder of control, STZ-induced diabetic rats (DM) and diabetic rats + hAFSCs transplantation (DM + hAFSCs). The immunoreactivity of 8OHdG can be seen in control rats (A), diabetic rats (B), and diabetic rats + hAFSCs transplantation (C) at 4 weeks, and in control rats (D), diabetic rats (E), and diabetic rats + hAFSCs transplantation (F) at 12 weeks. When compared to the controls, the expressions of 8OHdG in the diabetic bladder are increased at 4 and 12 weeks, but can be recovered to near the control level after hAFSCs transplantation. OD = optical density. Bar indicates 40 μm. *P < 0.05 vs. control group. #P < 0.05 vs. diabetic rat. N = 10 in each time point.
