Abstract:
Objective To evaluate the therapeutic effect of bone marrow mesenchymal stem cell (MSC) infusion transplantation via renal artery and via caudal vein in treating chronic kidney disease (CKD) in rats,and to compare the expressions of aquaporin1 (AQP1) and aquaporin2 (AQP2) between the two transplantation routes.Methods A total of 50 male SD rats were selected for this experiment.Two experimental rats were used to make preparation of bone marrow MSC.CKD model was established with infusion of adriamycin via caudal vein in 36 rats.The 36 CKD models were randomly divided into adriamycininduced renal failure model control group (A-C group,n=12),MSC transplantation through the right renal artery group (M-A group,n=12) and MSC transplantation through the caudal vein group (M-V group,n=12).The remaining 12 male SD rats were used as the blank control group (N group).One week after the last bone marrow MSC transplantation,the 24 h urine volume,24 h urinary protein content,serum sodium content and serum albumin level were measured,and AQP1 and AQP2 expressions in the kidney tissue were determined by immunohistochemistry.Results Compared with A-C group,the serum albumin level and 24h urine volume in both M-V group and M-A group were significantly increased (P＜0.05),while 24h urinary protein content and serum sodium content were remarkably decreased (P＜0.05).The 24h urinary protein content in the M-A group was obviously lower than that in the M-V group (P＜0.05).The AQP1 and AQP2 expressions in the kidney tissue in both M-V group and M-A group were strikingly lower than those in the A-C group (P＜ 0.05),but no statistically significant differences in AQP1 and AQP2 expressions existed between the M-V group and the M-A group (P＞0.05).Conclusion MSC transplantation can increase serum albumin,and lower urinary protein,serum sodium and the expressions of AQP1 and AQP2 in renal parenchymal cells,which has the effect on repairing renal injury of adriamycin-induced CKD rats.For a given period of time,the clinical curative effect of MSC transplantation via renal artery is better than that of MSC transplantation via peripheral vein,but the difference in curative effect between the two MSC transplantation pathways has no obvious correlation with AQP1 and AQP2 expressions.
