Abstract:

BACKGROUND: Common strategies for preventing diabetic nephropathy include effective control of blood sugar and blood pressure, inhibition of the rennin-angiotensin system and lipid-lowering therapy, but it is often difficult to get the desired results.
OBJECTIVE: To investigate the effect of transplantation of bone marrow mesenchymal stem cells on levels of blood glucose and urinary total protein in diabetic nephropathy rats.
METHODS: Forty-five Sprague-Dawley rats were randomly divided into three groups (n=15 per group): normal control group, diabetic nephropathy group and stem cell transplantation group. Rats in the diabetic nephropathy and stem cell transplantation groups were given single use of 60 mg/kg streptozotocin to make diabetic nephropathy models. The same dose of citric acid-sodium citrate buffer was injected in the normal control group. After modeling, 200 μL of bone marrow mesenchymal stem cell solution (2×106) was injected into the left ventricle of rats in the stem cell transplantation group, and then at 7 days after the first transplantation, the cell transplantation was conducted again. The same dose of serum-free L-DMEM was injected intracardially into the rats in the normal control and diabetic nephropathy groups. Levels of urinary total protein and blood glucose were detected. 
RESULTS AND CONCLUSION: At 1, 4, 8 weeks after treatment, the urinary total protein and blood glucose levels were significantly higher in the stem cell transplantation group and diabetic nephropathy group than the normal control group (P < 0.05). At 1 week after treatment, the urinary total protein and blood glucose levels were significantly lower in the stem cell transplantation group than the diabetic nephropathy group (P < 0.05). At 4 and 8 weeks after treatment, the total urinary protein and blood glucose levels were slightly higher in the diabetic nephropathy group than the stem cell transplantation group, but there was no significant difference (P > 0.05). These findings indicate that bone marrow mesenchymal stem cell transplantation in diabetic nephropathy rats can get good results in a short period, significantly improve the blood glucose and urinary total protein levels, but the long-term treatment effect is poor.
